For Eiscrushen must have the "grinder" (and at least it is not a percussion as cheap devices, make the snow from the ice!) A plastic hopper are plugged, which is designed down so that only appropriate to drop small pieces of ice in the reservoir , Of the first attempt is equal to a corner broken, and only through the load during crushing. This piece of plastic then found itself at second glance (clear) in gecrushten ice (Caipi ade.)
Incidentally, this is the same thing that has happened in our hand-ice crusher, but there just after 10 years ... In addition, the device makes itself idle pandemonium (and even more so when crushing). Anyone who has a model railroad, white, like a non-oiled locomotive sounds - it's quietly going on and then suddenly puts a tooth. So, only much louder.
I have no desire and no current requirement to test the device as a pure cheese grater (maybe it's because more durable). That's why I asked at Amazon.com to refund the purchase price and will ruefully return to separate or handsets.
