This ice maker is very easy to use, there are three sizes of bell shaped ice; (but there is only a little difference in them though.) It makes the same 'noise' as a fridge/freezer would, except you do hear when the ice is made as it empties into the ice bucket, this is preferable to an 'alarm' like some ice makers have.
I only wish the ice could be kept frozen once it is made, it does melt back into the machine through the slats in the ice bucket so no need to empty... you just have to start over.
