I am not a professional and have only recently returned to magic. This is one of the first tricks that I have purchased and the most expensive so far. The quality of the gimmick is OK, not great (the lines are not aligned as well as I think they should be). The page shown to the spectator first is a less bright white than the page given to the specatator. It was very noticable to me, but might now be in a less well lit room. I showed this trick to one person so far and they were fooled!
