Customer Ratings & Reviews

Best mouse I've ever used. No need for AA/AAA batteries as this mouse recharges via USB. The change lasts a very long time (at least several weeks of daily work and personal use). I have no regrets spending $100 on a mouse. I also like the tactile feel of the mouse buttons and the lack of the traditional clicking noise of button presses.

Buyers take note. This is a fantastic mouse, however, it now uses a different adapter (Bolt) than the MX Keys series (Unifying) over the previous 3 version, which is not cross compatible. This means it is no longer unifying and requires a different wireless adapter than the MX Keys. This is a change from the previous 3 model. I specifically bought this along with the MX Keys to switch between three PC and Mac computers (Unifying), as I was aware of the good reputation for pairing the MX Keys and MX Master 3 together, and I splurged to finally replace three keyboards and mice. Now, I'm stuck with either using Bluetooth only or returning it. The 3 model was no longer available, and this was marketed as the new upgrade and even displayed together at Best Buy. However, I discovered this change only after buying it. You have to read the fine print to learn this. I usually research these things to death before buying gear, but I trusted Logitech on this one. Lesson learned. Logitech, take note, if you're going to make a change this impactful it warrants more a more dissimilar model name. I've since noticed a lot of other angry customers on forums mentioning they fell into this same trap, so I just wanted to share it here to help inform others. Make no mistake, the 3S is a much better mouse spec-wise than the 3 series if this is not a factor for you. I still love this mouse and am debating whether to keep it and use with Bluetooth. You can get around this issue by using it only with Bluetooth, but there are technical reasons I prefer a receiver instead. If it weren't for this issue I would have given it 5 stars, but I'm docking two so people take notice. If you know this going in and don't care, it's a great buy.

I have had the previous MX series mouse for a few years now and wanted to upgrade. This one is better than the previous version the buttons are quite and scrolling is smoother.

I have a similar mouse that toggles between different devices. This newer model supports up to 3. The only drawback I have is the mouse doesn't store its USB dongle like my older one does. Overall performance is great, didn't have to install the logi software to use it. Works great on all of my PCs, Ipads, Androids and TVs!

Smooth scrolling and fits hand well. easy to conect to computer.

Very good mouse. Seamless with my M3 MBP, without a need to use the dongle. Feels good in your hand and has a satisfying click. I'm not a fan of this style of scroll wheel, but that's more of a personal preference. Overall, I recommend this mouse.

Excellent product l!! Much needed upgrade for my computer setup and helping with my arthritis.

I love love love this mouse. I had it less than a day before my supervisor tried it out and went out and bought one. Thinking of buying a second one for at home use since I keep forgetting it at the office. I can not recommend it enough!

Best invention ever! Instead of using a separate mouse for my Mac and then plug in and unplug the usb to interchange between my home laptop and work laptop to use the mouse, this makes life so much easier. I can interchange from my Mac to my home laptop and work laptop with a simple press of a button. I highly recommend!!!

Great battery life, feels high quality, clicks quiet but satisfying. Only downside is that the "flow" feature to take the mouse from one screen to another computer has a couple seconds or so of lag and it's easy to accidentally cross over so it's a bit annoying. I prefer to just click the button to switch.

Awesome mouse. Great for using one mouse with multiple computers or Bluetooth devices.

This is an excellent mouse. I have had an older version of the MX Master, and this is incremental improvements to an already top of the line mouse. Bluetooth connects perfectly, battery life is great, literally zero flaws.

This mouse looks so so good and works so great and accurate. I recommend this mouse whole hearted, i love using this mouse everyday at my home office, its really worth it. One charge lasts like 4 days so good enough. Buttons are smooth, my office looks great with mx meys keyboard and mouse

I work a lot on InDesign, doing 100-page proposals regularly. This mouse helps so much with scrolling back and forth. I have a relatively small hand but this is just perfect and comfy to use. Less of the carpal tunnel using those tiny, oddly curved cheap ones. Worth it.

Great mouse, use it every day and having the ability to use hotkeys on the mouse is awesome

Great mouse for office use, very comfortable and customizable.

The mouse feels great in your hand. You can easily connect to multiple devicies which I love. With the logitech option+ app, you can add many shortcuts which increases your efficiency. You can also add app specific shortcuts. This is truly a next generation mouse. Worth every penny.

This is the best mouse I have purchased all time. It is charged by USB and I have not had to charge it since I purchased it. I do turn it off after daily use averaging at least 8 hours of use a day. I have big hands the mouse fits comfortable. It has a quick reaction time for scrolling and clicking buttons. The product is pricey but so far worth it.

This mouse is fantastic, by far the most comfortable mouse for all-day use across multiple large screens. Sensitivity is solid, and I love the left-right scroll wheel. Highly recommend for both PC and Mac, and even works decent for gaming.

Very quiet and responsive, I initially thought the shape might not be comfortable but was thankfully wrong, i use it most of the work day and my hand feels less cramped. A little pricey but highly recommend.
