My sister in law made a few of these for the rug rat.
He's 7 months now. Not quite sure which way his hair should go, so I comb it straight up and let fall where it falls.
My 721 went a little wonky and I found a broke part. Figured if I have to tear it down I might as well build a repair stand for it. Maybe someday Zack will get some use out of it.
