I have been using this mouse for a long time now, and I have never had any problems. It is very simple, and should not break easily.

It's ok, but would have like to use the scroll wheel. Too expensive for a wired mouse with a defective scroll wheel.

Can't find reason for light changing from blue to red.

I use this mouse at work for CAD and Sketchup (3d modeling), which is heavy on the scroll wheel. I decided not to get a warranty because who gets a warranty on a [$] mouse? It stopped working after a month, even though the rest of it works....

This mice take less load and I play all gaming...this is way better than MX-518 mice!!! I had to buy that MX-518 mice at least three times!!

After about ten months, this mouse has started to freeze up. It usually isnt noticed, as I dont spend 100% of my time on the computer constantly moving the mouse across the screen, except for when I play games, such as first person shooters. I will...

I should have know there would be a problem with the scroll wheel. It's hard to scroll up with the wheel without accidentally clicking it. It's so sensitive. Well honestly I did not think it was a big deal. (even though it happened ALL THE TIME) But...

Bought this mouse because I use my laptop at work and needed something small and light enough for daily commuting.

The mouse broke after about two weeks of only slight use.

I've had it for around a month and no problems so far. As noted above, I like its simple uncomplicated design. And the lighted wheel is a cool feature. You can't go wrong at [$] I'm getting another for a friend.
