I makes at more ice than a refrigerator icemaker. It is not a bad noise but it would be nice if it could be made quieter.  Only real drawback is that the unit does not have refrigeration to keep the ice.  One would think being more than the price of a mini-frig it would be cost effective to make that capability at a reasonable price.  That said it does make ice every 5 minutes after the first batch. Not sure any frig can say that.
