before you buy this thing that appears awesome, read the 'mountain' of reviews regarding metal grinding into the ice cream during the cranking process. you're rolling the dice with 100 $ when you buy this, it's not worth it at all. we'll be sending ours back, burned on the first batch.
This ice cream churn was expensive and difficult to transport to where I live overseas, in a country whose unreliable electricity makes it a good idea. It came without any instruction booklet or recipes whatsoever, and ground a fine black metallic powder all over the top of the icecream. I suggest you look for a more user-friendly alternative with instructions and no black gunk.
