Forget what you know about wireless mice - the Logitech G900 Chaos Spectrum gaming mouse is a wireless mouse that not only matches wired mice, but also sometimes surpasses them in terms of responsiveness, with Logitech claiming 1ms report rate (that claim needs to be tested still).

Pros
Pro Just as reliable as a wired mouse
The G900’s transmitter performs well enough that it’s almost indistinguishable from other wired mice, in some cases even surpassing them in click latency tests. This, combined with its high quality sensor, makes it a great wireless option for a gaming mouse.
Pro Extensive customization
Aside from sensor and DPI adjustments, the G900 features extensive customization options. It has plenty of extra buttons that you can rebind with commands or macros. The scroll wheel can be changed to either free-rolling or notched scrolling. You can also choose to use it as a wired mouse, if you prefer. Full RGB lighting support lets you customize its look to suit your gaming rig.
Cons
Con Limited thumb buttons
Those switching from the G700 will find that they are going from 4 thumb buttons to two. Yes, the G900 allows for customizable side buttons of up to 2 on each side, but those who like to have more than 2 thumb buttons for gaming (especially MMOs) may find this hard to adapt to.
