Great mouse, has all the functionality I need especially with the action ring. I mostly use it for 3D modeling or BIM. I tried the MX 4, but it just wasn’t comfortable for me. With the M650 and M750 you get almost all of the same functionality in a different form.

I couldn’t be happier with this purchase! I previously used a generic $20 wireless mouse that started lagging badly, so I jumped on a deal for this Logitech mouse. It turned out to be the M650L model. The "L" version is specifically designed for larger hands and the fit is perfect. The tracking is smooth, the build quality is night and day compared to my old one, and it feels much more responsive. If you have larger hands and are tired of laggy budget mice, this is a fantastic and affordable upgrade!

I was shopping recently and saw this on sale so I picked one up. I have been using a great gaming mouse (not that I game) but it was a wired mouse. I really like the accuracy of my wired mouse but the cord does get in the way at times. I have had wireless mice in the past but the batteries would not last as long as I liked. I have been using this Logitech wireless mouse for about a month and I really love how smooth and efficient it is. The scrolling action is superb. The buttons have a nice reactive response as well. It is a joy to use. I also love how smooth the scroll wheel is. I have not had to change a battery which is nice. I definitely recommend this mouse.

I bought this for personal use. I like it so much that I take it with me to use at work. It is very smooth, quiet and comfortable. If they are still available next time I visit Sam's I'll buy another.

I use my M650 for hours each day. The capability to use it across 3 different PCs is a real time saver for me. I use the USB interface on one and Bluetooth on the other two. I also have some special keys functions I use. I initially thought it was a bit expensive, but it has paid for itself.

I've gone through 2 other mouse options before this (not Logitech), and couldn't stand either one. I put up with them, but between the lag or inaccuracy of those others, I couldn't buy this Signature M650 fast enough. I don't game at all. My days consist of audio production and daily business related tasks. It's perfect for what I need.

I Love all of my Logitech products, especially the fact you do make left handed or ambidextrous mice. Thank you for that !! Happy Logitech User

I switched from a Logitech G Pro wireless mouse to this because the former died after 5 years (pretty good for a mouse!). I should have just bought another mouse in the G Pro series. Still, this mouse isn't completely bad. Pro's: -Has a nice comfortable grip -Easy to set up -Very quiet Con's: -Heavy compared to what I'm used to -No onboard saving of mouse settings (this means if I switch to a right-handed mouse at work, I have to change the settings every time) I'll probably be switching back to the Logitech G Pro 2 wireless to save wrist fatigue. Those few grams of weight really do add up.

It is quiet and the battery lasts, but it is extremely laggy and makes every game hard to play, much more worth it to buy a cheaper mouse or a much more expensive one, right now I’m stuck with this one and I can use it but wouldn’t recommend it to anyone else or buy it again.

Vary disappointed with so called hyper scroll wheel. Does not scroll smoothly and as fast as prior similar Logitech mouse did, and as advertised. Hyper scroll works well when scrolling online, but not in other applications where I need it.
