At work at HVAC we use our drill bits a lot, I needed a new one and bought this one. Bosch GXL18V-233B25 18V 2-Tool Combo Kit, it actually arrived 2 days early. I've only been using it for a few days but don't see any problems with it, I've had Bosch b4 products. I have had Dewalt and Milwaukee 18v and 20v drills in the past, so far this drill works better than a drill. I have had a Dewalt 20V for 2 years. Highly recommended.
