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!!!

The shape is nice and comfortable on my hand with the contours and soft materials. It feels nice and sturdy. I really like the horizontal scroll, as a software developer I use it a lot when coding. The clicks are tactile yet very quiet.

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.

Fireeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

This is a fabulous mouse. Get over the price and just buy this.

This mouse is really smooth, select and precise. Coincidentally, it was on sale and had an old mouse to recycle and receive an additional 20% off the sale price for Logitech items. Very impress with this wireless mouse and best part, no batteries needed, just charge with ebclosed USB-C cable.

This mouse makes long hours spent using the computer far less irritating for the fingers, hand and wrist. Not a cheap mouse, but well worth avoiding acute or chronic irritation from repetitive motions over prolonged periods of use.

I wish my gaming mouse was as comfortable as this. the functionality for running through spreadsheets and other wide applications is by far the best experience. It is a very durable mouse as well. I toss this into my bag to commute everywhere and it doesn't show any sign of issue with that.

Easy to use and great support for hand. Unbothered for longer time use. Great shape

The best productive mouse without the doubt. Has amazing battery life.

Maybe for someone but not for me. I couldn't get this to feel the way I needed it to.

No dongle needed, but included for those without Bluetooth. Comfortable to use and great for use with laptops. I have one of these I use at work, and one I use with my laptop at home. Not quite a gaming mouse but I use it as one anyway on my laptop. For work use it's simply the best out there.

Great feeling, ergonomic mouse. I love the overall feel and the response time is great on WiFi or Bluetooth. My only qualm is that there is no onboard memory, meaning you have to install Logitech software to customize the functionality of any buttons.

The is a great everyday mouse, have hot buttons that you can set up with an app on your computer. This mouse has saved me so much time at work. Fully charged you can expect about a month before having to charge again… I use this M-F for at least 5-6 hours a day with constant use.

Ergonomically friendly! Dealt with some wrist/forearm pain due to using a standard mouse. The smooth feel and glide, along with the comfort and speedy scrolling makes for a great work must have.

I've had lots of mice and this one is king. Feel great in your hand, love the scroll wheel that automatically changes between clicky and free, and now I can't live without the silent click. Also love that you can use it Bluetooth or with a dongle and with 3 computers! It's good to be an MX Master ☺️.

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.

Logitech - MX master works well, nice addition to use USB type-c charging port. Works great on most any surface. Fast scrolling as advertised, configurable buttons, Bluetooth compatible as well as use with dongle. I like that it can be paired through the Logitech app to other anywhere dongles of the new version. Negative is no place to store dongle when traveling, no case. For over a $100 the quality is not as good as Logitech used to be.

Great mouse. Perfect size. Comfortable and quiet. Would highly reccomend!

Worth every penny. A lot of customisable buttons. Buttons are quiet. Can use simultaneously with couples computers with Flow technology
