Customer Ratings & Reviews

Worst mouse I've ever owned! Randomly disconnects for minutes at a time. Finally chucked it into the trash after failing when I was presenting during a Zoom meeting.

Logitech has another winner with the MX Master 3. I've used the original MX Mouse, the MX Master and now the MX 3, and this is the best of all of them. It's an iterative update to the MX Master 2S, so if you already have that mouse, this is probably not a worthwhile upgrade, unless the ergonomics of the back and forward buttons really bother you (which was my main complaint with the MX Master). Otherwise, the addition of USB-C charging is a nice upgrade. All of the other improvements are software related via Logitech's Options program, and thus backwards compatible with the MX Master 2S. The new scroll wheel functionality is nice, but not worth upgrading for. Overall, this is a great mouse and definitely worth it, unless you already have an MX.

WOrked for about a month, then wouldnt take a charge. Didnt think i'd need to get. warranty on a mouse. never had one die on me. But this was a big dub. Stay away

Actual color much darker than appears online. Returned because I was looking for something more on the light silver/ white spectrum….

I've been on a hunt for a decent mouse for well over a decade. Logitech seems to have decent products, but all have an Achilles heel of some sort (ie, inaccurate scrolling, double clicking over time, ineffective solar charging, etc). This is the first mouse I've found that has performed flawlessly for over 2 years now. I'm a Salesforce Developer and frequently scroll through pages of csv files or lengthy code blocks. In nearly every task, this mouse is precisely what I need. I keep hunting for anything that could be remotely better, but honestly, I don't know if that's possible (maybe improved thumb clicking?) It's expensive, but buy it used or on sale and it will be the last mouse you'll ever need.

I have a previous model of this mouse that is light years away from a new design. Mouse is made with cheap parts and much lighter than previous model.

Does not work will with my iMac When you shut the computer down the keypad Does not work with Appledoes not automatically think Bluetooth

The mouse is working great but I just realized it did not come with a charging cable. My mouse is running low on battery. Please send a charging cable.

I’ve mentioned in other reviews that I like Logi’s computer input devices. As proof, I now have three generations of the MX Master mice. Between the first and second, there were minor improvements - not really enough to notice. This new version is in though, and it has a few notable changes that need talking about. Out of the box, you’re getting the mouse, a universal dongle for Logi devices, and a USB C charging cable. The mouse itself is slightly bigger than a standard “PC style” mouse - you’re getting all the same right-handed ergonomics that can be expected from the shape and previous generations. Previous generation users, note that it is _slightly_ smaller than the previous Master 2S, but not in a bad way. I’d also like to call out that the device charges with USB C - this is a fantastic touch and I’m glad that my phone charger once again can pull double duty as a charger for my desk peripherals. The layout of the buttons has slightly changed - the vertical scroll wheel has moved up and become a little freer to scroll, while the back/forward buttons are now below the wheel and slightly larger. Personally, I’m not a fan of the new placement as you now need to move your thumb a bit more to pick which function you would like to do. This is 100% personal preference - I can see how the new design could be considered more ergonomic. The biggest change though is the primary scroll wheel. Previous generations had the feature called SmartShift, which would switch the wheel from clicky step-based scrolling to free-wheeling after scrolling a certain number of lines in a certain time window. The wheel was audibly clicky when in the former mode, and even louder when re-enabling the clicky mode - to the point that it might have become a nuisance to others in an office situation. Not so with the Master 3. Logi has introduced the new MagSpeed feature which performs the same task as above, only using electromagnets. The effect? You can’t hear the clicks unless you are really listening for them - they are only felt by the user on the wheel. I can’t say enough about how cool this effect is and how much I love just how silent this device has become. No longer do I wonder if I’m annoying coworkers from my mouse making too much noise. Finally, Logi has improved tracking quite a bit - at work, I’ve got a shiny white desk which previous generations had an issue tracking on. That problem is completely eliminated with the Master 3; I’m able to use the mouse on the desktop just as easily as on a mousepad. Think I’ll keep the mousepad, but Logi states the Darkfield technology that runs tracking should allow me to track even on glass. Overall, aside from the positional changes of the vertical scroll/navigation buttons, Logi has taken a ton to heart and has improved the mouse by leaps and bounds. I’m quite happy using this product daily - and I think my coworkers are quite pleased with the silence.

Frequently, randomly disconnects, rendering this mouse basically useless. I opened a support ticket with Logitech and never heard back.

I got the new Logitech MX Master 3 mouse along with their new MX keyboard and use them in tandem at the office. The MX mouse shares some of the same features as the keyboard so it’s a logical tech upgrade (see what I did there?). What a great productivity combo. I love the ergonomic styling of this mouse. It fits in the right hand very comfortably assuming you are right handed. Button placement is perfect with 5 functioning buttons, 1 middle button scroll wheel and a 2nd side scroll wheel. There is yet another button next to the middle scroll wheel that toggles the wheel between a free scroll or a tactile scroll (I prefer the tactile scroll). The breakdown on the but… • You have the typical right and left mouse buttons • You have the somewhat typical middle scroll wheel/button • On the left side you have another scroll wheel which will scroll between open browser tabs (why hasn’t anyone thought of that before?). Love this feature.. Love this feature.. Love this feature. • The two side buttons (below the side scroll wheel) allows you to go forward and back in your current browser tab history. • Lastly the thumb rest button (stealth gesture button… I pressed this by accident and was pleasantly surprised) switches to task view making it extremely easy to switch between apps without having to dive down to the taskbar with your cursor. Also if you hold this button it acts like gesture control. I love this feature too! Depending on what applications you are using the buttons and scroll wheels provide intuitive controls such as undo, redo, horizontal scrolling (great on Excel spreadsheets). Fully programmable with optional Logitech software as well. It’s extremely fast and accurate with 4000 DPI sensor resolution. In tandem with the MX keyboard which allows you to connect to 3 different devices and easily switch between them so does the MX mouse. So, you can be connected to multiple computers and switch easily between them like a virtual KVM switch. It also allows you to seamlessly copy or move things from one computer to the next regardless of which compatible operating system you are using (example… Windows desktop to a Macbook). It comes with a USB-C cable for charging. Logitech claims 70 days of use on a full charge. I haven’t had it long enough to determine what my actual usage is so mileage may vary. This mouse is fully compatible with Windows, Mac and Linux operating systems and easily switches between them allowing you to share work between up to 3 devices. Along with the MX Keys keyboard these two new devices from Logitech are my new daily drivers for the office. Highly recommended!!!!

Over priced piece of junk. Logitech has fallen off, terribly. Expected a lot more! MX keys is the same.

IT IS DEFECT. DO NOT PURCHASE THIS MOUSE> THE SCROLL IS COMPLETELY BROKEN. AND JUST KEEPS SPINNING.

I previously had the first generation of the MX Master mouse. This mouse makes a few changes and upgrades from that original, but it is largely the same. The form-factor is essentially the same, which in my opinion, is a case of don't fix what isn't broken. I find the MX mouse to be very comfortable and ergonomic to use, and fits very comfortably in my hand. Many computer mice seem to put comfort and ergonomics somewhere near the bottom of the list of priorities. This mouse seems to make that first, and then Logi built around that. One of the key differences between this and the original MX mouse is the placement of the side scroll and forward/back button controls. The forward/back buttons are much easier to reach and hit on this mouse, and situated in a much more natural position. This makes it effortless to navigate webpages or other applications with just my thumb. The side scroll is also much larger and has a nice smooth scroll action. Though personally, I would prefer if it had a click action, and that was one of my wishes of the original MX mouse too. The default action of this side scroll in a web browser is to switch tabs, but without clicking, you don't know if you scrolled too much or too little, and sometimes you don't switch tabs, but sometimes you switch too many. It's a bit frustrating and makes me not use it as much as I would otherwise. The gesture button, which sits in a sort of hidden way under the thumb is nice, and is largely the same as the original MX mouse. I don't particularly like the default gesture actions because I feel like it requires too much mouse movement to activate the gesture, but fortunately, like all logitech products, this button is fully programmable to do whatever you want. The scroll wheel has also has been updated and uses a new "MagSpeed" technology, which I assume means it has some sort of magnetic control instead of mechanical for the click/free-wheel action. You can feel this difference when using the wheel, and it makes for nice scrolling. The only minor complaint I'd have is it can be a little loud... not with scrolling, but when you stop, it kind of "bounces" forward and back a bit and it makes noise. I found it a little worrysome at first, but I got used to it and don't really notice it much anymore.

The mouse you want for work the only thing that I don’t like is it doesn’t have onboard memory.

This was almost unusable on my Mac, it kept slipping randomly both hardwired and Bluetooth.

Only good for 1st year. Performance degraded after 1 year.

Randomly stops working for about 2 days then works again...disappointing and frustrating!

I bought this mouse 3 years ago and it's still running flawlessly. The best thing about this mouse is the configurable button on the side that can be configured to do various things (per app too). Another cool thing is free scrolling feature that makes going over super long documents a breeze.

I’ve been using the MX Master 2 for home & business for several years. Every time the mouse died (usually because the left-click mechanism eventually failed), I’d search the market, only to find that Logitech’s MX 2 was still the best mouse available. So, I’m really excited that Logitech upped their game again with the MX Master 3. I expected only a few tweaks, but was pleasantly surprised with the upgraded form & feel. The Good -Fatigue: I’m a heavy user (~10 hours/day). So, when I replaced my standard employer-issued HP mouse with the MX 3, I immediately noticed a major reduction in hand fatigue, in just 1 day, after switching to the MX 3. And the physical stress relief wasn’t just in my hand, but all the way up to elbow & shoulder. -Feel: It’s a bit weightier than the MX2. The mold feels a little larger & better suited to my hand. The surface is also much smoother than the MX 2. -Smooth Glide: For the 1st time ever, I ditched my annoying mouse pad. The mouse works perfectly on my desk. No more need to lift and re-center the mouse on the pad all the time. -Scrolling: Smooth & fast! They also fixed that awkward click when toggling from ‘ratchet’ to ‘free-spin’ mode; so, I toggle between modes often now. -Logitech Options App: I definitely recommend downloading the App to your PC. I had several questions re: buttons I rarely use, and the Intro Tour addressed them all. You can create different settings for each App that you use (Word, Excel, etc.). -Receiver: One receiver can pair up to 6 devices, preserving USB ports The Bad -None. However, only time will tell if the internal parts are of better quality. It’s a shame to lose an expensive mouse because one small internal piece (left-click) fails. Overall: 5 big stars! Logitech really thought of everything with the MX 3. I keep discovering new features I like, the longer I use it.
