The original Logitech MX Master mouse made some waves when it launched in 2015, primarily from what was considered a high price tag. What could a $99 mouse offer that its cheaper rivals couldn’t? On paper, the specs didn’t add up, but what Logitech created was more than the sum of its parts in the pursuit of creating a nigh-perfect productivity mouse for power users.
The success of the original MX Master mouse and its followup, the Master 2 (and refreshed Master 2S), made expectations high for the third generation of Logitech’s flagship productivity mouse. Fortunately, as both a productivity-enhancing tool for power users and simply a luxury experience for office tasks, Logitech’s MX Master 3 Wireless Laser Mouse fires on all cylinders, proving that you don’t need two stumbles before hitting it out of the park when good things come in threes.
- Unboxing and Setup
Despite its tall profile, wide base, and metal scroll gear, the mouse only comes in at 5 ounces (142g), which is on the heavier side for wireless mice but still within reason for a large mouse. First impressions are mixed - the material quality doesn’t feel particularly higher than other wireless mice with a rubberized grip and typical-feeling plastic mouse buttons. Scroll wheels are quite nice to touch and use, and the mouse glides a little more smoothly across a mousepad than some higher-end gaming mice I’ve used. Included in the box is a USB-C charging cable, a Logitech Unifying Receiver, and a quick-start guide that directs you to the MX site to download the Logitech Options software.
The Logitech Options software is a 200MB download that, as strictly a driver companion, would be the weakest part of the entire Logitech MX experience. It requires an account to be created or linked to a Google or Facebook account to use the software, and doing so backs up your settings to Logitech’s own cloud to let you sync your keyboard settings across devices. The software is somewhat basic and allows for the usual litany of function key reassignments, but besides Logitech Flow and basic setting adjustments there’s little that the software adds to the MX Master 3 experience.
A nice feature of the Logitech’s MX device line is that they can be paired to 3 different devices once configured with the Logitech Options software. The mouse can be paired via Bluetooth to any compatible device and this connection saved to any of the three device slots on the keyboard. These slots can also store a pairing to any Logitech Unifying Receiver and switching between them is a quick button-press on the bottom of the mouse.
- Design & Build Quality
What Logitech took away in flair and color moving from the MX Master 2S to the MX Master 3, they made up for in comfort and sheer ergonomics. The grip is very natural, comfortable, and every button is positioned and weighted perfectly so there’s no accidental clicks, scrolls, or presses you didn’t intend on. The positioning is so good that I only remembered the existence of the forward + back buttons that were literally resting under my thumb for a week, never once activated by mistake. That there are three buttons the thumb can use and activate without moving it out of its cradle, that are still easy to activate without accidentally triggering them in normal use, is simply outstanding. Common shortcuts can be mapped via the Logitech Options software and make this into a productivity-enhancing beast for your daily work.
The switchgear used in every button feels extremely solid and durable, exhibiting no play and making extremely satisfying clicks. The thumb wheel scrolls with a good amount of resistance, and the main scroll wheel changes between free-scroll and ratchet mode with what feels like a magnetic click on and off. Scroll the wheel fast in ratchet mode and this “clutch” disengages, letting the wheel spin freely then ratcheting back into step once it comes to a stop. Might be a little too much fun to play with if you’re a chronic fidgeter. Extremely impressive all around.
My only criticism on the design would be that it’s not an ambidextrous mouse, nor available in a left-hand variant as of this writing (October 9, 2019). Lefties shouldn’t be left out on this one.
In daily use, the MX Master 3 glides and tracks excellently across my mousepad, yielding precise, weighted cursor movement that rarely needs compensation adjustments even when moving across three screens. Both slow, precise and fast, sweeping motions are effortless once you get used to the momentum that a heavy mouse generates.
One of the hallmark features of the mouse’s optical sensor is its ability to track across any surface (per Logitech’s claims), even glass. Sure enough - tracking across a mousepad, wooden desk, cloth sheet, leather, and indeed even the glass of a tablet all worked phenomenally, with the glass feeling oddly even more precise than the other surfaces.
As mentioned in Design & Build Quality, there’s no shortage of buttons on the mouse, and using them in conjunction with Logitech Options to map common commands and keyboard shortcuts (which can be set per-application, thus allowing commands to change based on the active window) definitely showed potential for speeding up my workflows over time. With all the shortcuts literally at your fingertips, it’s hard to think of a situation where they would be a hindrance rather than a boon for getting things done quicker.
- Logitech Flow
Logitech Options’ killer feature is Logitech Flow. Essentially a software-based keyboard-video-mouse (KVM) switch, Flow lets you control two computers using a single set of Logitech MX (and presumably other Logitech-branded) devices. While the trick would be neat enough in itself to control two computers, the software synchronizes both machines’ clipboards automatically, allowing seamless copy-paste and drag-and-drop integration between them. This works for both Windows and Macintosh machines, and you can indeed mix-and-match operating systems. The only limitations to Flow are that it must be used with two machines on the same local network, and both machines must be on and awake.
Flow was surprisingly easy to set up and sync between computers. Once enabled I had no trouble using a single mouse pointer and keyboard between two machines. While the software works as intended, moving from the “local” to the “remote” machine and back took a moment for the mouse pointer to move between machines, and there was a noticeable delay, maybe 2 or 3 frames, between mouse movement on the local machine and the pointer updating position on the remote one. I found myself needing to move just a little slower and more deliberately on the remote machine, but not to the point where I felt it was anything more than a minor inconvenience rather than a major impediment.
The software worked flawlessly in my testing otherwise, and truthfully the ease of simply copy-pasting text, images, files, anything between two machines after just a couple minutes’ setup is revelatory. I could almost make my recommendation for the MX Master 3 on this alone.
The wireless range on the mouse to a Unifying Receiver will vary based on interference - if it’s installed on a rear USB port on a desktop tower it may lose connection much easier than when it’s installed on the front. Regardless, the mouse had no issue working on any surface elsewhere in the room, no matter what obstructions I put in the way.
Though not advertised as a gaming mouse, it certainly could be used for a few casual matches of popular twitch-shooters as latency was adequate throughout testing. At worst, the MX Master 3 feels like it could be a frame behind the action on-screen but no more. Switching between this mouse and a Logitech G305 Lightspeed, the G305 felt a little more responsive.
In an attempt to overcome the latency deficit of the MX Master 3, I plugged the mouse in directly via the included USB-C cable, and found that it’s unfortunately a charging port only. It will need to be connected wirelessly to any PC to use it with one.
- Bottom Line
Hardcore gamers, you will want to look elsewhere. For everyone else, the MX Master 3 is to mice what German automakers are to cars - luxury experiences with the price to match. A $99.99 MSRP is a tough proposition when most other wireless mice and even the older MX Master models can be had for half as much, but Logitech set the benchmark for mice a third time over with build quality, features, and performance that still put them at the front of the pack. Factor in the killer app that is Logitech Flow and it shouldn’t be a surprise I’m giving this one praise. Highly recommended!
The Logitech MX Master 3 cordless mouse is the ideal companion to the Logitech MX Keys keyboard. It is a very fine product on its own merits, but when paired with the MX Keys keyboard the duo provide the finest interface/control devices you will ever find.
I just posted a review of the companion Logitech MX Keys keyboard and the next three paragraphs are copied from that review because I think it is important to learn about the manufacturer, Logitech, when you are investing in these high quality peripherals.
I have to confess that I just love Logitech products – they are always superbly engineered, are packed with great features and have always given me reliable service.
Logitech was founded in Apples, Switzerland in 1981. Its first product was a computer mouse in 1982 that was adopted by several computer manufacturers (including Apple.) Later it was the first company to offer a replacement mouse to the consumer market. Logitech introduced wireless mice, optical mice and trackballs. By 2008 Logitech had produced over one billion mice.
The Logitech mouse was followed by a wide variety of high quality products including a handheld scanner, keyboards, a digital camera, webcams, speakers and microphones. It acquired Harmony, the industry standard for programmable multi-equipment remote control devices, in 2004, then purchased Ultimate Ears, a creator of outstanding Bluetooth speakers, in 2008, bought Jaybird, a premier manufacturer of very fine Bluetooth earphones, in 2016 and most recently, acquired Astro Gaming in 2017.
Here are the key features of this great mouse:
• Logitech MX Master 3 wireless mouse M-R0077 (receiver C-U0008)
• Dual connectivity (Logitech Unifying USB receiver or Bluetooth)
• Wireless range approximately 33 feet

This mouse has a beautiful shape which allows you to comfortably rest your hand on it while it cradles your thumb. There is a subtle grooved texture on the thumb rest and the right side (where your little finger would grip) as well as a non-reflective, anti-slip black matte texture coating on the main body of the mouse. This is perhaps the nicest exterior I have ever seen on a computer mouse.
Just above your thumb are two programmable buttons (typically assigned to back/forward), as well as the thumb wheel which can be used for various functions (such as magnifying/reducing the size of text or spreadsheets). Pressing down with your thumb on its rest activates another feature, the gesture button.
The bottom of the mouse has four low-friction glide pads, the recharging port, an on/off switch, the Easy-Switch button to change to other linked devices and the Darkfield optical sensor.
For me, the two most important aspects of the Logitech MX Master 3 mouse are the electromagnetic scroll wheel and the Darkfield high precision sensor. The scroll wheel can switch from a ratchet mode to a free spinning mode by pressing a button behind it. In free spinning mode the scroll can whip up and down documents, spreadsheets or Cad-Cam plans very rapidly and effortlessly. The Darkfield sensor is a Logitech innovation which will operate on any surface, even glass! This is particularly useful to those of us who like to work on glass-topped tables – no more need for mouse pads!! The resolution of the sensor is set at 1,000 DPI but can be easily changed to any value (in 50 DPI increments) from 200 to 4,000 DPI. While there are some mice with even higher maximum resolutions (up to 16,000 DPI) 4,000 DPI will meet the needs of almost any application. This mouse is more than adequate even for the most stringent demands of Cad-Cam and Photoshop duties.
The MX Master 3 mouse automatically changes the button assignments to defaults appropriate for the application you are working on. For example, the thumb wheel will scroll side-to-side on spreadsheets, magnify/reduce text on documents or change brush size in Photoshop. I was amazed by this feature when I had both a spreadsheet and a Word document open on my desktop. The feature changed without any action on my part when I put the mouse pointer on each document!
The ability to pair with three devices at once is another nice feature. I linked it to my desktop PC, my Fire tablet and a laptop I use frequently. This gives me the freedom to use multiple devices without changing my interface (keyboard and mouse) and from the same position at my desk.
Another useful element is the rechargeable battery power used by the mouse. There are few things as frustrating as working with a wireless mouse and discovering that the battery has become depleted and that you have no replacements handy. More than once I have had to scavenge a needed battery from a remote control so that I could continue working on my PC. That will not happen with the Logitech MX Master 3 since it recharges from any USB port and you can continue to use it while the recharging takes place. You can expect up to 70 days usage from a full charge.
One last point – this is a very tough and durable device! Three times (yeah, I know, I am really clumsy) I accidently knocked it off my kitchen counter (where I was using it with one of my computers) and it survived a 42 inch fall onto a hard surface with no damage or scratches!
There are many other slick features (copy and paste from one device to another, quickly applying an alternate set of mouse controls, etc.) but you will find the core features described above to be more than sufficient justification to buy this superb mouse. I urge you to pair it with the similarly outstanding Logitech Keys keyboard to experience the full functionality of that duo.
I am delighted to give the amazing Logitech MX Master 3 mouse my full and enthusiastic recommendation!
I find the MX Master 3 mouse very comfortable to use and the MagSpeed scroll wheel is wicked fast. The ability to make Application Specific settings for buttons, gestures and pointer/scrolling is a powerful feature.
It is really nice being able to reverse the scrolling direction of the scroll wheel in Windows 10 using the Logitech Options software instead of editing the mouse properties in the Registry!
Easy Switch is great. You can pair the MX Master 3 mouse with up to three computers using Bluetooth or use the included Unifying receiver. Quickly switch between three computers by tapping the Easy-Switch button on the underside of the mouse. Trying to share a regular wireless mouse with more than one computer can be difficult at times. Much nicer being able to tap a button and quickly switch between three computers. If you are using two (or three) computers side by side, picking up the mouse to tap the Easy-Switch button becomes tedious. It would have been nice to have the button on top.
A full charge using the included USB-C cable should last 70 days. The mouse gets constant use with our desktop computer and it holds a charge so well I leave it on all the time. It will let me know when the battery gets below 10% and I can still use it while charging. If you don’t want to use your wireless mouse with a wire, a quick minute charge will last three hours.
I’ve switched back and forth between Bluetooth and Unifying receiver connections on Mojave and Windows 10 and see no benefit to using the Unifying receiver and tying up a USB port if your computer supports Bluetooth. The mouse remembers button/wheel assignments when switching between Bluetooth and Unifying connections or if you remove the device and add again later.
Logitech Options software:
The Logitech Options software is easy to use, and it can automatically back up your settings to the cloud. Much nicer than their buggy G Hub software. The settings for the “Wireless Mouse MX Master 3” are organized within Mouse, Point & Scroll and Flow panels.
The Mouse panel has two views of the mouse, overhead and left side. There is a checkbox to swap left/right buttons. You can customize the Middle, Wheel mode shift, Gesture, Forward and Back buttons plus Horizontal scroll. Selecting them on the Mouse panel presents a pop-up list of Recommended actions but you can expand to the full list (40+) organized by Navigation, Productivity, Media Control, Mouse Commands, System Commands, Quick Access and Do Nothing. The Horizontal scroll has a list of 4 Recommended and 8 Other actions. Settings default to All Apps or you can enable Application Specific settings. There are presets available for some of your installed apps and you can enable/disable application specific settings anytime without losing your custom settings.
If you assign the “Gesture button” action to any of the buttons you can then select between Windows navigation, Media Control, Pan, App navigation, Zoom/Rotate gesture presets or Customize your own. Gestures are executed when you hold down the “Gesture button” while moving the mouse. The “Navigate between apps” gesture is strange because it functions backwards. It is similar to using cmd/alt + tab on the keyboard but moving the mouse to the RIGHT scrolls through the apps to the LEFT and vice versa.
The Point & Scroll panel lets you set the Pointer speed, Scrolling speed, Scroll direction, Smooth scrolling, Thumb wheel speed, Thumb wheel direction, SmartShift, SmartShift sensitivity, and Fixed scroll wheel mode. All of these settings can be applied to All Apps or can be set Application Specific.
The Flow panel is where you Enable and Setup Logitech Flow. The feature allows you to switch between computers by moving your cursor to the edge of the screen and quickly copy-paste text, images, and files between them.
Using the MX Master 3 mouse with the MX Keys keyboard:
Duolink is a great feature. You hold the FN key on the MX Keys while you move the MX Master 3 mouse or click the buttons. You can define another complete set of actions and gestures for the mouse and toggle them by holding the FN key.
Tapping the Easy-Switch buttons on the MX Keys to switch between computers won’t automatically switch the MX Master 3 mouse. You will need to switch both. It would have been a great feature to automatically switch the mouse when you switch the keyboard like a KVM switch.
I have had all of Logitech's MX Master series and have yet to be disappointed at any of the releases. Logitech has missed their mark on some of their products, this isn't one of em. Great change in the "stance" and overall design in the third edition of the MX Master. Plus the sweet gray colorway is a nice (welcome) change and allows for me to easily differentiate between my MX Master 3 (Black) for my Custom Desktop PC and my other MX Master 3 (Gray) I use for all my various tablets I use in my workflow. The gray MX Master 3 is surprisingly not too much of a fingerprint magnet. Overall I am stoked on the newest MX Master from Logitech.

The best mouse ever!! I can’t be more excited about this and I have had it for over a month. The cursor move lighting fast! The scrolling on this is heavenly!! Sometimes i spin it for fun. Do yourself a favor and watch the video on logi on how to use it. When the guy showed the hidden button I was geeking out!! If you deal with spreadsheets, forget it get this one!! The fact that I can scroll left to right is so nice!!! Then the fact that I can switch up to 3 devices!! I feel like the most efficient employee in my office. Spending more on yourself pays back to you!!
Purchased to work with image editing software. Found it works well with every program, browser, game.
Seems to hold a charge quite a long time. I've had the mouse for 7 weeks and plugged it in twice only because I felt it might be needed. The software shows current charge and always shows full charge.
I have it connected via Bluetooth and I can't tell the difference from when it was connected through the dongle.
Haven't tried the mouse on other computers but I understand it can be simultaneously connected to 3 computers.
I think it's the best mouse I've ever had, I've had many. Thinking about getting more, hoping to see a sale.
The buttons are somewhat programmable. Some programs come with preset buttons depending on the program. Some of the presets are unique to the program. Wish some of the presets were available to other programs.
Hi JosW, Thank you for your five-star review! It is greatly appreciated. Continue to enjoy your device. If you ever need assistance, please contact Logitech Support on the website. LaShonda from Logitech

I purchased this mouse and was excited by its ergonomic features. It's certainly the most comfortable mouse I've ever used.
I also appreciated the buttons that I could map for custom functions. The mouse is, without question, the best one I've ever had...but only in theory.
That's because the company's handling of a problem leaves much to be desired.
Let's back up a bit.
So, I've purchased four mice (two USB, and two Bluetooth, including this one) and two keyboards from Logitech in the past year alone.
I'm a big fan. (And literally tell everyone at work who will listen, about Logitech. I know... odd... but I do.)
So it was surprising, not to mention disconcerting, when I contacted their customer service to ask why the mouse displayed an orange (not green or red) light, and, ultimately, the matter wasn't handled to satisfaction.
Let's be clear about this orange light: This was a very distressing discovery after I paid $109 for the mouse.
The customer service rep, who was friendly and whom I have no complaint with at all, knowing he was just doing his job, took down all my information (name, address, phone number, etc.), only to tell me, later, it would be better if I just return it to Best Buy since I'm an Elite member and it's within the window.
Well, here's the problem: I trust Logitech and threw away some of the packaging from the mouse.
Maybe it was just the plastic cover; I don't know. The box is still available, along with the instructions for the mouse, but I don't feel right about sending just part of the packaging back.
It's clear that I received a defective unit. That's because there's an orange light (which the manual makes no mention of — just green or red LEDs) and the battery doesn't hold a charge for more than three days. That's why I was stunned to learn that some of you have gotten 70 days (really?!) out of one charge.
In my view, Logitech should have just shipped me a new mouse since this one is clearly defective.
That's why I had to give this a two-star rating. The mouse is perfect for my hand. I mean, PERFECT.
But they didn't stand by their product, which wasn't a matter of returning the product to Best Buy at that point.
They manufactured a defective product and, in all my years of purchasing consumer electronics but, really, anything at all, once it becomes a question of defect, the manufacturer immediately ships out a new device at no charge to the customer.
Especially after the customer service rep and I had days of back-and-forth messages and I took the trouble of answering the questions asked of me and providing my personally identifiable information. Only for it to not even be used (Um, GDPR much?)
But I digress.
Most companies would ship out a new unit by priority mail.
Especially after all the inconvenience I endured.
But that didn't happen here.
So, two stars.
This is the best mouse I have ever used with a computer. It synchronized easily with my Omen and I have not lost connection since. It even alerts me to when it needs to charge.
Build quality is fantastic and the mouse fits perfectly in my hand,
It took a little bit to get used to it, but now I would never go back to any of my old mice.
I will admit that $100.00 for a mouse seems expensive, but it is well worth it.
If all you do is scroll on Youtube, or through your photos, this is not your mouse.
If you need more control for Sketchup, photoshop or similar programs, then yes, this is your mouse.
PS. You will want to shut this mouse off when you are not using it to conserve the battery.
The analysis of all aggregated expert reviews shows that the reviewers are positive about durability, size, reliability and design. Editors are less positive about price.

A:AnswerI have and do own many, many Logitech devices. I've never had an issue with any of them over the years. This mouse replaced my original MX Master, which still works perfectly after years of dependable service. So, I don't feel there is a need to purchase the extended warranty through Best Buy. But, if you are overly demanding of your electronic equipment and have had issues in the past, then a warranty may benefit you. Zip~
A:AnswerYes, using the free Logitech Options Software you can customize the top or side scroll wheel to control volume on your PC. You can download that free software from us at Logitech here https://support.logi.com/hc/en-us/articles/360050549994-Download-Stub-MX-Master-3-for-Mac
A:AnswerIt’s precise and there is a ton of settings to switch between for each application. So my settings for photoshop is different than illustrator and different for web browsing. Also, button is on the bottom and you can switch between computers. I would have liked it better if you didn’t have to flip the mouse over but it’s easier than switching out a USB plug, so pretty easy, question is what’s your level of laziness, mine is high…
