Processing: is very good and nothing seems shaky. The mixing mechanism comprises a roller and sprocket system which distributes the cards by placing them in the middle into two piles.
Handling: simple. Turn deck in the middle and at the crank. Here, you can still adjust how wide should be the ejection slots. This prevents the ejection of too many cards to one side. The bounce the cards against the wall of the discharge chute harms not really much, but causes a constant chatter that maybe some people find unpleasant.
Criticism: Unfortunately, the machine is intended only for German / European music. American game leaves like poker cards or many board games are too wide and remains simply stuck in the shaft. Here was spared a few millimeters, which would have improved the product key. Therefore deduction.
Conclusion: If you mix a lot, the machine should be set. Because it is battery-free, unpleasant surprises stay off well. Who has a lot of cards in somewhat wider format, should have recourse to another machine.
