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.

My third try for this one. I really like the quiet buttons. It scrolls randomly and this one has a glitch in the movement sensor.

A much better product than the M355 mouse. More comfortable for my wrist due to the raised position of my hand. The scroll wheel works much better as well.

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.

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.

Great product. I have medium size hands for a female. Easy to use. Purchased 2 one for windows and one for a mac

This mouse is truly silent. It has a nice weight, the trackball has a really good feel, and it connects effortlessly. The battery life in this thing is 10/10. An absolute win. Please make it in cute colors!

I bought this mouse because I was having a lot of pain using the magic mouse that came with my iMac. This mouse is so comfortable, and I started using it seamlessly. It's quiet, it's smooth and the optional buttons are convenient. I love it!

Nice mouse. I grabbed it in a pinch (lost my other one)and I like it. I hadn't purchased one in a while and this one is quiet - you don't hear the click sounds.

Perfect for everyday computing and reliable! It was also a great price at Sam's Club. It's comfortable to use and a great value. It works for home, work, and travel. It is also silent and doesn't click.
