its not an impact driver.. its a screw driver, just with the 1/4" hex drive quick chuck, and adjustable clutch.. i have this tool already.. its very nice. its a pretty good upgrade from dewalt's old 7.2 nicad screwdriver. 12v , lithium, nice handle and a belt clip makes this a nice choice.. i drywalled my entire house with the old 7.2 screwdriver.. the adjustable clutch on this makes it a really nice way to disassemble and re-asseble anything where screws hold plastic parts together, like tools or toys..
thats a good price just for the batteries and charger..
