The top one is working okay with decent torque. Second one is working but intermittent torque indicating worn cogs. Third one has seized screw in battery cover due to leaking batteries. Have managed to remove the batteries by removing side cover. Cogs from this could possibly be used to make one good tool from the two of them. No driver bits but these are available on E bay. Please use photos as part of description. Work from 2 x AA batteries not included.
