This was a bad muse, didnt reapond or lagged on my mac.

It was too complicated to get set up correctly. I didn't have a working mouse so how could I do that myself?

It really did not make a difference from previous mouse, i will try the lift maybe my wrist stop hurting.

The scroll wheel is became very loose after a few days of using it.

I've been a fan of logitech mice for quite some time. They are of great quality and work/fit well in almost every scenario, My current m9use is the MX2 Anywhere mouse which is perfect for my on-the-go/work laptop. However, my desktop still needed a quality mouse to use with and this one fit the bill perfectly. The ergonomics of this mouse is pretty much perfect for my hands. I have Med/Lrg sized hands so the contours of this mouse just fit great for me and the buttons are all within reach for my fingers. Connectivity is pretty standard fare here so you can connect with the USB dongle or via bluetooth. I don't know why but it would be really great if Logitech would incorporate some place to put the USB dongle in the mouse when not in use. Would really mean a lot since I seem to always lose the USB dongle for my other mice. Fit/feel of this mouse is great. The L/R buttons are almost silent when pressed and the configurable buttons are well within comfortable reach of your hand. You can program the buttons as you see fit so there's lots of customization there. Scrolling is fantastic with this mouse and customizable as well. There is a multi-device connection feature on this mouse however I haven't been able to test it as of yet. With this, you're able to pair the mouse to several different devices, laptops, tablets, etc., and use one mouse across all of them. Sounds like a great idea however, for now, I haven't been able to utilize this feature as of yet. Overall, a great mouse for for your needs and especially if you have larger than normal sized hands. The side scrolling button is a bit weird for me only in the sense that I've never had a mouse with this. It'll take some time getting used to but definitely a nice added feature on this mouse.

If you're familiar with the MX Master line of mice, then this will be entirely familiar. It was already a good product, but Logitech has still managed to find way to tweak the design. First, the Logo Options + software is now out of beta, and the minor issues have been fixed. Besides giving you enhanced ability to redefine what each button does, the software also allows you to assign functions to buttons depending on which app you're currently using. So, for example, the side scroll wheel could switch between tabs in your browser but scroll side to side in your Excel workbooks. The main applications that come with preset tailored functions are Chrome, Edge, Excel, PowerPoint, Teams, and Word, but you can add just about any application on your computer for customized settings. The main scroll wheel still does its thing where it will sense when you're trying to scroll a lot and start to spin freely for extended scrolling. You can also turn that "clicking" off and on for the scroll wheel just by clicking it, but I found that it still scrolls in small jumps on the screen, so I prefer to leave those magnetic "clicks" on for regular use. I also really appreciate the presence of that side scroll wheel over having to use buttons or push the center scroll wheel side to side. It's just better ergonomically. And overall, the ergonomics of the mouse are still superb. The main left and right click buttons are quieter, as advertised, but I'm not sure how important that really is. If you haven't updated your mouse in awhile, this is good option.

I have used every iteration of the MX Master series mice and was looking forward to getting this newest version. It definitely does not disappoint, and I highly recommend this mouse. Packaging is typical for Logitech and refreshingly simple. It comes with the mouse, USC C charging cable and the Logi Bolt USB receiver (I have never needed this for any version of this mouse as I connect via Bluetooth). The only issue I came across was with setting this mouse up. I had been using the MX master 2S mouse for a year and it connected immediately. This one took about 20 minutes as my 3 month $2700 laptop would not pair with the product. I then tried to connect through the Logi Options software but came to find out this mouse needed a different software called Logi Options + in order to unwrap all the great features, assign buttons, etc. Had to remove Logi Options, install Logi Options +, then reboot and then it connected quickly. It would have been nice to know it needed a different software from the beginning – would have saved a lot of time. Operation of this mouse is flawless and unbelievably works on ANY surface, even a clear glass top table. Programming the buttons through the software was simple and of course you can change the speeds of the cursor movement as well as the 2 buttons near the thumb under the thumb scroll to your liking. Ergonomically, this is the best feeling, most comfortable mouse of the MX series. Overall – I highly recommend this mouse as it does what it touts and does it extremely well.

Stains easily, super choppy performance, app is ridiculously clunky. Do not waste your money.

Overall good mouse, there are a lot of customization options, but it's too big I cannot comfortably click on the flat gestures button area while using the mouse I've figured out a way to make it work for me, but you can't use the side buttons to zoom in/out which would be really nice. The horizontal scroll is nice as well, but not necessary Great mouse, but would not buy for full price (bought this for $85), I would try out a couple of other options if I hadn't got this on sale

The right mouse button didn't work real well. Also has limited programmability. I expect more for the money.

The mouse itself is very well made and works well. If not for the misleading info on the box I would give it 5 stars. The box however is misleading in that it gives the indication that the mouse can be used both wirelesly and wired. To be clear, the mouse will not work in a wired configuration, it only uses the USB C cable to charge.

The Logitech MX Master 3S is a great Mouse that you can take anywhere and it will work with up to 3 different devices which is a welcome versatile feature. First thing I did after taking the Logitech MX Master 3S out of the box was charge it with the included USB C cord, and Logitech claims the battery will last up to 70 days which is more than enough lasting power for me, if I get a month or so I’ll be happy. Time will tell. The Logitech MX Master 3S comes with an included Logi Bolt Bluetooth receiver but I didn’t need to use it for any of my devices. I paired my Logitech MX Master 3S with my MacBook, a Windows Gaming Laptop and an iPad Pro and once paired switching and working with different devices back and forth was seamless. The Logitech MX Master 3S is fully customizable if using the Logi Options+ software which is available for PC and Mac. Scrolling is smooth and overall operation of the Logitech MX Master 3S is fantastic. The Logitech MX Master 3S is my go to Mouse for all my devices now.

This thing works and feels better than I ever thought a mouse could be.

NOT FOR ME............................................

Finally - All the features of MX series with softer clicks and newer wireless tech, and improved tracking on shiny/glass surfaces! I'm already a BIG fan of the MX series, owning a full-size MX Mechanical keyboard and a separate Craft keyboard for my second workstation at my desk (for my creative work!). I also have both an MX Master 3 and an MX Vertical mouse, and the MX Anywhere portable mouse for travel (spoiler alert, I'm a Logitech peripheral fan!). Alas, I loved the MX series, but the MX Master 3 (and the MX Master and MX Master 2 I owned before it) all suffered from very loud click sounds from the primary left and right mouse buttons. Some people like the click, but those people aren't married to my wife! :) The MX Master 3S is the perfect companion to my new MX Mechanical keyboard - Its smoothness doesn't disappoint. ALL of the MX Master features are here, including customizability, scrolling control (choice between stopped/clutched and smooth scrolling and compatibility with Logitech's own receiver format, and bluetooth PCs, tablets, phones and other compute devices. There are a few quirks as well, mostly due to a generational leap that Logitech is making across the MX series starting with the Master 3S and MX Mechanical: - This mouse is NOT compatible with Logitech's UNIFYING receivers that they've been including with peripherals for YEARS now. They have upgraded it to a new technology called Logitech BOLT which will replace UNIFYING in their lineup. BOLT has some technical advantages, such as reduced USB bandwidth and I believe better coverage/reduced latency but this will disappoint those who are only upgrading one peripheral and expected backwards compatibility with their other desktop components. BOLT is the new UNIFYING at Logi, but you'll need to upgrade everything to take advantage. BOLT devices can't work with a UNIFYING receiver, and UNIFYING compatible devices won't work with a BOLT receiver. Its a lose-lose on compatibility. Thankfully Bluetooth is Bluetooth and supports all, but if you use the receivers, you'll need two to support mixed old/new standards. - Just as with the hardware, the software is being replaced also- Gone is support for Logitech Options, the keyboard and mouse customization software for the rest of the MX series, to be replaced by Logitech Options+, which gets nary a mention on their Options website. I spent about 30 minutes troubleshooting how I had the latest version of Options and STILL couldn't see my MX Master 3S in its configuration screen. The good news here is that Options+ DOES support many of the older MX series items also, so upgrading to it in a mixed estate should be no problem. All in all this is a generational change, which will delight some and infuriate others, but I'm so happy to have this device, as well as the rest of the EXCELLENT MX Series, in the stable. I loved it so much I went out and added an MX Mechanical to the set (which I will review separately) just to have everything on my station on BOLT and Options+ and to take advantage of its improvements. The new MX Series devices are worthy of the name!

If you've worked with any of the previous versions of this mouse, you know that they fit your hand like a glove--assuming you're right-handed at least. The 3S is no difference. It fits comfortably in the palm of your hand. The two main buttons and scroll wheel feel great. The horizontal scroll wheel and button on the left where your thumb rests are all within reach for the one finger. The largest upgrade from the previous version of this mouse has to be, hands down, the clicking noise - or lack thereof! The difference is night and day! This new mouse is so incredibly quiet when clicking the right and left buttons. It's advertised at 90% quieter, and I believe it! If you're in a quiet room, especially with a partner studying or something, the reduced clicking noise alone will save you from ugly looks from them. The tracking sensor on the 3S is rated at 8,000 DPI, which is double that of the pervious version. While I cannot say that I've noticed any difference, twice the rated performance is cool to know. Not only does it provide even better, more precise tracking of movement, but it also helps performance over a wide variety of surfaces. I have a mixed material desk (wood and glass). While the mouse is always on a mouse pad, I have tried it on the clear glass surface and it worked just fine. Connect this mouse up to three devices via Bluetooth or the included USB dongle. The mouse does have a USB-C port for charging, so you can use your own cable or the included USB-A to -C cable. The software allows you to customize the various buttons on the mouse and enhance its capabilities on both Mac and Windows. The software also allows you to seamlessly switch between screens with Logitech Flow (a software feature). I've used it on my desktop and laptop and works okay, I guess. It's just not how I work, but it's there if you really want to take advantage of it. If you already own the MX 3, I wouldn't say the upgrade is worth it. If you're coming from a 2S or earlier version, or are looking for an incredible mouse, then I would absolutely recommend the MX Master 3S.

An optical mouse is nothing new for any of us in 2022. Even wireless mice are probably considered old school by now. So, why is this the better option than what you already have? Ultimately, this does what every other mouse does, but just a little bit better. It comes with a few extra buttons (and wheel) which are very easy to customize with the downloadable software. In particular, I really appreciate the sun wheel that sits directly below your left some along with the included back/forward buttons. You can customize any of these buttons to whatever keystroke you’d prefer, but I find the default settings to be perfect for me. Assuming you are right handed, this may be the most comfortable mouse I’ve ever used. Tracking is fast and very precise, and while it is not marketed as a gaming mouse, it seems more than adequate for that application, as well. Compared to my wired “gaming mouse“, I really can’t discern a difference (although I am admittedly not a hard-core, third person shooter, kind of guy)…. Wireless performance is seamless, as would be expected. One of the nice features of this particular mouse is that it can be connected either via Bluetooth or using the wireless dongle connected to a open the USB port. I can’t discern any particular latency with either option. It does have a onboard memory that will remember multiple devices, so it is easy to switch use from your desktop to a laptop, for example. Wow this does have some nice bells and whistle‘s, ultimately what matters is whether or not it functions as you would expect. As already stated, for me this mouse is a solid improvement over my prior pointing device, and just seems a bit more polished in every way. For something that we use for probably 75% (conservative estimate) of our computer interaction - which for many of us can be several hours a day - this is more than a worthwhile investment. Two thumbs up!

After 3 years of heavy usage, I was able to upgrade from the Master 3 as my main mouse (which is now my travel mouse) to the Master 3s. Though the look of the mouse is practically identical to its predecessor, the mechanical upgrade does make a big difference. One of the biggest pain points from the Master 3 was how loud the clicking noise was. As a designer, I do click a lot and it was the most annoying thing to other people. When you're clicking away in an isolated room, it probably doesn't matter as much but if you're next to someone using the mouse as a designer - its pretty distracting. I didn't realize until a colleague commented on it. But with the Master 3s, I was blown away how quiet the clicking was. There's also more sensor sensitivity options for those with higher resolution screens, I usually set mine at 1800 DPI,you can set it up to 8k max. Same as its predecessor, you can easily switch between different devices and adjust the settings of the horizontal/vertical scrolls, and other buttons depending on the program you're using through the Logi options app. Which as a designer, I fully take advantage of programing zooming in/out for the scrolling, copy/paste buttons and much more. Maybe because the mouse is newer the side scroll has a little more friction when scrolling which I personally like more. The design of the mouse allows my full hand to rest comfortably on the entire mouse. This essentially ruins me when I try to use the traditional mouse that is less comfortable and makes me long for my logitech master 3s. The only downfall is the USB-A bolt receiver, as it is incompatible with the other logitech devices and I would have to use a USB-A to C converter. Waiting on logitech to finally give us the USB-c. But overall no connection issues with the receiver or through Bluetooth. Overall, logitech never fails to deliver.

Right off the bat I can honestly say that I recommend this upgraded Logitech MX Master 3S Wireless Laser Mouse with Ultrafast Scrolling being it's made by Logitech. Inside the package is the new upgraded MX Master 3S mouse, Bolt USB receiver, and USB-C charging cable and user documentation. The Bolt receiver is resemblance to the Unifying Receiver from the last model, however, this connects via Logitech Options+ software and not the regular Logitech Options software. The mouse itself is identical to its older sibling the MX Master 3 Wireless Laser Mouse, that I reviewed a couple years ago. On looks alone, everything looks the same. Simply pop the Bolt USB Receiver into a free USB port on your laptop/desktop and its ready to go. However, its recommended to download and install the Logitech Options+ software as stated above. This allows you to tweak the settings to your liking. The build quality is solid and sturdy as we've all come to love about Logitech products. In this upgraded model, Logitech fined tuned an already awesome wireless laser mouse with ultrafast scrolling and made it better. Precision and movement is like buttery smooth. The DPI is now 8000 compared to 4000 and the left and right button clicks are ever so quiet. In the MX Master 3 you can hear and audible click when you press down on the buttons, but on the 3S there's no click sound. This was the first thing I noticed after I got everything installed and loaded. My favorite feature on both the 3 and 3S is that ultrafast flywheel. You can spin that scroll wheel as if you're on The Price is Right, or you can press the button below the scroll wheel and switch the wheel mode into more of a line by line scroll. This mouse can also be connected via Bluetooth instead of the Bolt USB receiver. Bluetooth mode is great for when I want to connect it to my iPad.

Good features and build quality. Something about the design hurt my hand/wrist/arm, so I returned it.
