The biggest disappointment with this drill is that it won't charge below 32 deg F, pretty major setback for winter work that I've never seen on any other model, and I've used many. Where other chargers blast the battery with juice until it heats up enough to accept a charge Bosch just shows a red error light. Even when I brought it inside and it finally warmed above freezing it only trickle charged at cold temps taking hours to fill. I called Bosch and they said that the Litheons are the same way so I returned mine and ordered a NiMh of a different brand, more amp hours and maybe I'll actually be able to use this one. Also the softer break "durashield" housing is more prone to scratches and won't help you anyway if you drop it on the cheesy plastic chuck my model came with.
