I have been given this card shuffling machine. I've always wanted a manual. With the power of the engine am fully satisfied, the cards are mixed well, just playing cards with many beneficial. If the clusters are not distributed evenly on both sides twice better mixing. It may be that the cards in the middle collide advantage of the manual, simply turned briefly back and off we go on!
I can not judge how educationally valuable as a machine is and how much fun they have to do really, but certainly saves time :)
