On a purely personal note, this whole mess has been depressing. I'm not a rich man, and splurging on a fancy mouse was a real treat for me. It's hard to see this much money go to waste on a piece of junk.

Just about everything about this mouse is great; Good shape, good button layout, feels good to use; In every respect save reliability, this is probably the best mouse I've ever used

The mouse randomly cuts out or stutters while in use; At first I thought it might be an issue with the surface I was using it on, or maybe I was letting the battery get too low; But the problem persists even when I've confirmed the thing is fully charged, and no matter what surface I use it on.

It is my 5th Logitech MX mouse. I also have a MX anywhere 2S. I've been using MX mouse since it was first launched. It never disappointed me. Super comfortable and smooth.

Not quite sure what the difference between the 2s and the first version is... Either way, I have both and love them both. I have the 2s in white and the previous version in blue. As clean as the white one looks, it gets dirty EASILY! I'm constantly cleaning with a wet wipe to get the smudges off.

I have paired this with the dongle on my notebook and via Bluetooth for my Surface and have had no issues, also has a great response rate for spanning multiple monitors.

Got a good deal at Rakuten. Excellent mouse stylish design very suitable for people with large hands. Love the thumb wheel and the secret button. Buttons can be customised based on requirement. Smooth Scrolling light weight mouse

The MX Master wireless is Logitech's current flagship mouse, which comes with a spec sheet that's almost as long as a spoilt child's birthday wish list. As well as a stunning, ergonomic design, it has a clever speed-adaptive scroll wheel, the ability to connect to three different devices at once and...

Excellent performance; Striking; ergonomic design; Clever 'Easy-Switch' function; Speed-adaptive scroll wheel

Bluetooth sometimes cuts out; Expensive

Productivity mice generally aren't very exciting, with a standard selection of buttons and perhaps a relaxed, hand-friendly ergonomic design. The Logitech MX Master certainly fulfills those expectations, but goes several steps further to produce one of the most feature-packed wireless mice we've...

A sturdy, comfortable mouse with a brilliant range of features. You get used to the shape very quickly, and you'll wish every mouse has its features. Battery life has so far been great - it came out of the box with 2 of 3 LEDs lit, and is still on 2.

I bought this after owning the Magic Mouse, very glad I went for this as it is far better ergonomically and doesn't make my hand feel so squashed up/strained when using for long periods of time.

Bought this for the flow technology to use on 3 computers. I already had the MX Master which I love, without the flow working it is exactly the same. At ￡90 I'd expect it to work as advertised and contacted them with the issues. Didn't get a response over 2 weeks until I put a comment on facebook.
