Nice concept, sorry execution...
I had the Black & Decker version. I haven't seen it in a long time but it may still be around here somewhere. It used the same VersaPak batteries as their low end battery power tools--everything from drills to leaf blowers--from the late '90s and early 2000s. I think I paid about $20 or $25 for it at Kmart. Even at that price, it was definitely not one of my better purchases. Even with a full charge, the motor simply wasn't powerful enough to accomplish anything.
