In my experience the adhesive they use for the grips on steelseries mice doesn't last long, so worth looking into reviews before you buy.
Had one of these for a while, bought to replace a failing Steelseries Sensei - feels pretty nice in the hand though it's a little heavier than the Sensei. Don't really see the point in the screen as it's not in an easy to see spot but the vibration alert thing is quite useful.
Looks awesome. Thanks!
