I love this Logitech mouse. It has a smooth feel and even though it is right handed, feels comfortable in my left had. Got it on sale for a great deal.

The left click button on BOTH mouses (mice) I had required multiple clicks to function. I returned the first and purchased another, and had the same issue. One, I can understand a manufacturing error. Two is a production quality control issue.

Too sensitive on right and left click, no software adjustment to compensate.

this mouse is smooth, quick, easy and functions perfectly! fits my hand just right and love the red color

A left handed mouse, finally! Works great. i didn't configure the side buttons because i don't really need them.

It's a great mouse with good ergonomics. It did take me a while to get used to the very light touch on left and right buttons.

Keeps dropping bluetooth connection. Works for a while after restart, then suddenly drops the connection.

A big too large for my hand it works well. Overall, I'm happy with it.

Connects fast, reliable connection, works, no problems.

This mouse has no downside, no quirks; it just works.
