The slush ice maker works great. The first time has not worked with us. The cup should far longer than 3 hours put in the freezer until the cold mat is really chilled (like a frozen cooling pad, crumpled and fixed). In our freezer to stand at -18 degrees at the coldest point. Tastes best and it works only with apple juice or multivitamin juice. As in the manual is it does not work with Light drinks and also not with unsweetened beverages. Then wait 1.5 minutes, that is leave and not fiddle already tuned. After properly knead well. But that is not in 20 seconds because you have to have a little longer Knead, but also create children. Only form small crystals. Then you have to continue to knead until the juice to real slush ice. Perfect!
