That show is absolutely NOT intended for young teenagers. It is rated mature, which is closer to XXX than PG-13. We set our parental controls so anything rated higher than PG-13 requires a passcode.
I had plans to build one for mine, but I bought a couple sets of these instead.

They have worked really well so far.
Has anybody tried to reopen an old hole with the SM electric? Or tried to drill connecting holes? I have very little experience with shaver blades, I've always had chippers.
