Question: How many shuffle times are needed  after a game?
Document: Never having seen a card deck shuffler before, I was disappointed that theseBicycle 1-2 Deck Card Shufflerrequire lots of hands-on "help" while the little spinner pulls the cards in. Sometimes they go in chunks so we have to shuffle many times. I was greatly disappointed that 1 of the 3 identical shufflers that I purchased doesn't work at all and has to be returned.
After many "tests", it seems to take about 7 or 8 shuffles are needed to thoroughly shuffle, MINIMUM. 1  side gets stuck often so the other side spits out a bunch of cards in order. It is also loud and klunky. There is many other card shufflers on the market much more efficient than this one. Dissapointing being bicycle brand.
Our family has had a Brookstone World Series of Poker 2 deck shuffler for several yrs. First, those who could shuffle kidded us wimps who used the shuffler. Over time, everybody has come to enjoy the shuffler during game nights when we play round after round. We decided we needed one at the beach condo, so I ordered the Bicycle version, thinking the people who made cards would make a good shuffler. The shuffler works fast & does a fine job, though an occasional card gets hung.
Took it out of the box, put brand new batteries in it, and proceeded using it. It worked three or four times, then one side of it stopped working all together. We put another new battery in it, and it still wouldn't work. It was so embarrassing. We had our friends over to play cards, and the shuffler didn't last through one complete game. Very disappointed to say the least.
The shuffler does its job quite well. With a brand new deck, however, it's necessary to shuffle several times for a good result. It's a bit noisy, of course, but tolerably so. Certainly a great boon for someone with arthritic hands!
Could no longer find this item locally. Amazon had several varieties. This is very efficient, durable, and mixes cards thoroughly. Useful when playing virtually any card game. While somewhat noisy, the duration of the shuffle is brief.
You would think that a card shuffler would shuffle the cards alternately from the two sides into one pile. Most of the  time the shuffler is doing nothing. Then it will kick in and send a stack of 5 to 20 cards from one side or the other, and then sit and spin for a while before it sends another stack of 5 to 20 cards. To effectively and randomly shuffle the cards, one would have to put the deck or decks through at least 8 to 10 times.
Bought this for our lunch-break uno game at the office, it mostly fails to shuffle the non laminated Uno cards. However we tested it with some pvc Bicycle brand playing cards and it performs flawlessly. Wish there was somewhere to get a set of PVC Uno cards!It jams the uno cards because being unlaminated they tend to have more cohesion, sticking to each other. The laminated cards are slick and slide easily over each other so it never jams with them!
The left hand side of the shuffler malfunctioned after using it 3 times....it stopped feeding the cards in from the left side..I returned it to Amazon...
This shuffler is nice for the price. Although at times 4-5 cards would still be in the same order after shuffling. Running it two times would solve the problem, but doing that isn't really saving THAT much time. Fun to have though.
Answer: yes
