My fingerprint has faded on this mouse. It is tiresome, it doesn't have the proper rubbery feel of a fast mouse, and worst of all, the scroll wheel makes noise, doesn't respond immediately, and feels like a broken jumbo toy. The battery cover is loose and the button doesn't indicate on-off.

Overall pretty good. I got it as a gift for my daughter. Unfortunately, the second one had a problem but they told me they will replace it for me.

The mouse was good as long as it lasted, even for light games (e.g. LoL)
But after 3-4 months suddenly when I moved it left it went up, when I moved it down it went right, etc. In other words, the controls were reversed and it became unusable.

It needs a mouse pad otherwise it has a problem on any surface.
It is expensive, the battery runs out quite quickly
