I expected more from hitachi! Coming from a carperter of 18 years, this tool will not make it in the field with me. I use it in the shop and around the house. I do like the drill itself and the flash-light is great. If you put charge on the battery for your next use, it will be dead less that 2 days in a nice warm shop. I can leave my makita in the truck for weeks in 20 degree weather an it will be ready to go when you need it.
