Does not simply

Bought as a birthday present for our son from dealer Goods and gadgets on Amazon this Slush Maker.
After freezing overnight -> juice pure and stirred for 20 minutes. A Slushy is still not came of it. It's not working. Therefore, I give the item back.
Unfortunately, I am now also on the return postage to the dealer because it declared itself unwilling to accept this.
Who else is like it pays come to the right address.
