DeWalt sent me a brand new replacement. worked intermittently. found that the contacts (inside the screwdriver handle) were not making good contact with battery. Had to (ironically) use a hand held screwdriver to bend the contacts (inside the handle) so would get a solid contact. I have noticed the DeWalt is not as good quality since black and decker took over. Just hate to spend 300.00 on a Milwaukee when the DeWalt only cost 80.00
