Query: Disappointed

The shuffler we ordered does not feed properly. At first we thought it might be something we were doing wrong, but since there were no instructions included, we kept experimenting, reducing from two decks of cards to just one to shuffle. Sometimes that seemed to help, but sometimes not. We finally figured it is not working right. But we missed the cut-off date to return it by a couple of weeks. We would not think of selling a defective product. My uncle uses this kind of shuffler with good results. We are very disappointed and it looks like our only recourse is to return it for a part of the cost.
