I have a "Chopper". It is a clipper, not a shaver like the "cleanhead". It works just OK. It seems to be underpowered unless you use the boost button. Wahl clippers are much better, IMO, because the power is there when you need it, no need for a boost unless you run into something particularly coarse. Of course Wahl doesn't offer any of their clippers in "hot rod yellow".
