Craftsman Professional 28128 20-volt Lithium-Ion Cordless 1/4" Impact Driver with Quick-Release Collet & LED Light —
I bought this tool to expand my 20 volt lithium set. I already owned the circular saw, drill, and flashlight. Great for use as an electric screwdriver and works great for driving long screws into wood. It's a little on the heavy side, but it feels sturdy and the battery life is excellent. I recommend it to anyone who already has the 20 volt lithium set.
