Summary: Drill endurance is terrible. 5 year old Panasonic 15.6 volt and 3 year old Ryobi 18 volt beat it up everyday. Protocol is 3 battery swaps in an 8 hour work day. It's only 6 months old. Bottom line, A RYOBI OUT-PERFORMS IT!
Summary: I recently purchased this drill despite the warnings I have read here related to chuck run out. After charging the battery and firing the drill up for the first time, I was disappointed to find that the chuck was dooing the hula!
