This arrived quickly and was well-packaged. It is easy to use. Some things we recommend in its usage: 1) Use a nice, stiff, clean deck (or two decks) of cards, 2) ensure that the cards are neatly pressed into place in the storage troughs (especially at the stack bottom), and 3) crank the handle fairly fast until all the cards have dropped below. Following these tips has worked very well for us.
