Had mine about a week. Only shot PCP air rifle and 22lr so far, but velocities are believable and consistent, no super fast or slow shots. Hasn't missed a shot yet, and I've tried as far as 3 feet behind and 2 feet to right of muzzle. At 50 yards purposely aimed it at next target over left and right, picked up every shot. Only thing so far I can't figure out is how to resume a previous session. If it is possible, I cannot figure out how to do it. Overall very pleased.
