I really don't know a lot about it, except my "EX" husband bought it. He bragged and bragged to the neighbors about it. Said He could roll a pack of cigarettes in less than three minutes.
 I'm sure he used it around three times cause I was the one had to go buy his supply's at the corner store.
Well let's just say he found himself in a rather uncomfortable spot a few weeks ago when I arrived back home early from a dinner party that had been canceled unexpectedly.  I suppose he during all the excitement The Zen Roller (as well as all his belongings  except the little bit of clothing he was wearing) must have slipped his "mind" (and I use that word very loosely)
I know he said he paid right at 100 for it but it's worth about 20 to me on a new hairdo.
