Review on Decker BDCSOA Offset Attachment Screwdriver by Ken Pinell

I have this and find it a great accessory for Black and Decker 4V Screwdrivers which come with a tip end designed to accept this tool. Sooner or later, many of us have to turn a screw in or out next to an obstacle. That little affection can help. Not high accuracy, but sufficient for the intended function. My first device had a pronounced sticking in the transmission, the second device was sufficient.
