Tasty By Cuisinart Ice Cream Maker (Green)

My brother, who is a professional culinary instructor, was the first to attempt to use this product. He has a similar product from Cuisinart (and has had it for years). He wanted to see if this newer product could perform as well as his other, older model. He was also considering adding this product to his Amazon store, as he teaches professional online courses. He (and we) were deeply disappointed to see that this product could not even finish one dessert. All instructions were followed, and there was nothing wrong with the contents he was trying to mix up. It is really unfortunate. Plastic parts?? Unbelievable.
