I was fed up with the cheap electric Medieval torture devices. Operating this takes a little getting used to, but couldn't be simpler. Never tugs, doesn't dull thick blades with big bevels), never runs out of juice, and never fluctuates wildly between zero and 3 million RPM depending on angle of attack, relative humidity, and whether it got laid recently.
I ordered one. Tired of the damn hairs making my nose itch like hell.
