Besides getting my husband a professional poker set for Christmas (which I have reviewed separately), my husband's brother also gave him an automatic card shuffler.
This is a really nice item. It will automatically shuffle one or two decks of cards very easily and efficiently. It operates on 4 AA batteries (of course, batteries are never included). With the push of a lever, this shuffler will do a great job of thoroughly shuffling your cards. My husband is pretty good at shuffling cards by hand, but this is still a very nice item for him to have. Plus, it's really great for me. Whenever my family and I play cards, I have a hard time shuffling them because I have small hands. This card shuffler will probably be of more use to me than my husband.
The automatic card shuffler is made by Cardinal and is for ages 6 and up. I think it's really a nice gift, and children and adults alike would probably get a lot of use out of something like this.
