I’ve had a couple of different mice brands thru the years, mostly Logitech, but also a couple of the MS variety too. They all work well, but this one seems slightly more ergonomic to me, and it’s sleep mode seems to do a great job with battery life. The thing that really sold me though was a recent experience I had with my 3 year old blue one. I moved my laptop downstairs and put the mouse in my fleece jacket pocket. I forgot about it and a couple days later washed the jacket. Transferring clothes from the washer to the dryer, there was my favorite blue Logitech mouse. It was scuffed up, the battery cover was laying a couple inches away and the battery was under some other clothes. I thought it was done but set it on the counter and let it dry for a couple of days. Got a fresh battery and to my surprise, it still works. Can’t beat that. You can see the scuffs and some scratches in the pic, but still works great.
