We have purchased several battery powered card shufflers both for ourselves and as gifts. We play a lot of cards and use the shufflers most of the time. We purchased this one as a "gag" gift but found that we liked it much better than the battery powered ones. It does a great job on single decks. Not quite as good on double decks. But, you can split the deck and shuffle several times. The crank does tend to disengage sometimes when winding. But, you just have to be careful. AND, there is a second crank included just in case you do wear the first one out! All in all, a great buy and a good price.
