Works well for the most part. One thing I noticed that I've never seen before is that after 3-5 pulses of drilling, the chuck on the drill continues to loosen, causing the drill to slip out of the unit. I couldn't find a solution to this problem and have tried to reproduce this exercise on my other battery powered drills but this is the only issue that has this issue. I have to be very selective about the environments I use this tool in.
