I use it as our primary pit gun for racing in an endurance road racing League (WRL). Over the course of a weekend we heat cycle a few sets of tires, and may have to pull wheels off during the race, etc. We use the gun to break nuts off, and to get them somewhat tight, final torque is done with hand torque wrench (to 75 pounds). The pit gun has worked great in its first weekend. Plenty of power for the above use. Battery life seems adequate - we used the same battery all weekend. I will say the battery seems to recharge super fast. The only drawback is the carry case is kind of cheap and doesn't stay tightly shut very well - the latches don't work particularly well. Hasn't flopped open or anything, just not very high quality.
