Cons

Con Bad Palm Grip
With a design that is not ergonomic at the back and side buttons that are so far out it is not a recommended mouse for a mouse user who prefers palm grip.
Con Has input lag and smoothing
Being that this device is using a laser sensor there is expected lag and smoothing.
Con Battery life
The battery lasts about a day, depending on what sensor settings you use. This is somewhat mitigated by the ability to just plug in the cable and keep going, though.
Con Large base
The G700s's bottom is exceptionally large, and dirt/grime often gets stuck on the bottom and causes tracking issues.
