The ESP is great, and the only feature that I use to be honest because I don't want to risk a ban. 3 months so far, no detections or hackusations. Updates come fairly fast and if there is a delay, they've compensated for time that it was down.
More features were added recently and the ESP now tracks weapons and ammo.
Grizz and UP have a good reputation. If you're looking to rage and burn through a game key, there are cheaper ways to do that. If you're looking for stability and a steady edge in the game on your main account, this one gets my recommendation.
