Manual Card Shuffler - great invention. The fun factor increases significantly when one otherwise quite poor and the cards "mixed" has. And everyone wants now !!! Selfphase 10 cards go well. One must be careful when inserting, a little oblique to the mixing mechanism insert out then it's great. The noise level depends on the pace, which may be loud or soft ... We are super happy. Excited we are to the life expectancy of such a machine. We play a lot of cards. Wait.
