I purchased this item to replace my old mouse that had just given up the ghost. One of the other reasons for purchasing this was that it had cable connection. I like cable because I don't have to worry about my mouse migrating and getting lost.

I have owned 20+ Logitech mouse, this is the bu far the best day-to-day mouse! Doesn't feel like a budget mouse at all, very comfortable to hold, best for palm grip (my hand length is 17cm). Performance is more than sufficient.

I recently purchased two of these for the office I work at, where they have been used on a daily basis now for about a month. Today, when someone sat down at one of the computers to use it, the mouse at that computer wouldn't respond. We tried plugging it into another machine and still no response.

It's larger form factor is comfortable for my large hands. I prefer wired mouse devices (my wife calls this mouse a "rat". Regardless, the wired mouse interface has no delay in responsiveness, which unfortunately was the norm for my previous large form factor mouse which was a wireless, and the lag...

Doesnt feel cheap, feel comfortable after trying 4-5 different mouses including Logitech models. The hyperfast scrolling feature and side buttons are very useful for me. I am very happy with this purchase that I found a right mouse

Husband was tired of changing batteries on his wireless and this mouse works much better. He's a happy camper!

Great mouse that I use every day for work. I work a massive spreadsheets and that hyper scroll feature really helps out tremendously. Also great for web browsing.

Great hyper scroll feature Very nice ergos

Tile feature of the scroll wheel could give you a bit more feedback once you use the feature; Sometimes I feel that I did not actuate the mechanism as the user feedback is minimal

I've had 3 of these purchased around the same time and all three the left button has become bad - the contacts must be loose because it thinks you've double-clicked when you've single-clicked and thinks you released the left click when you haven't.

No neew to worry about battery

Good quality; precise

No so far

Comfortable side buttons and ergonomic design will not make your hand tired quickly.
