Good mouse, some complaints though

Strengths:

Feels amazing to use
Looks really nice
Optional cable is a huge plus
Braided cable never gets tangled unlike my old Logitech G5
Nice lights
Slides so smooth

Weaknesses:

Left and right mouse buttons are really sensitive, can barely rest fingers on them without them clicking (not really a weakness, really depends on personal preference)
When holding right click, the button contacted the scroll wheel and made it difficult to scroll (I don't know if this was just my mouse, but this is a main reason I returned it)
Battery life is ok, I got about 8-10 hours out of it before it died (set to 1000Hz polling, 1 minute sleep, and low brightness light)

Summary:

(Continued from Weaknesses)
Dock has tiny notch for mouse to sit on, sometimes it won't charge, make sure that the charging indicator comes on when you dock it

Overall this is a really nice mouse, but the click+scroll issue and the average battery life made this mouse not quite worth it. $130 for a wireless mouse isn't terrible, but it is when you realize you'll probably be using the corded option more than the wireless mode.
