Product review (5 stars): Noisy,  as expected,  but pumps out thimble sized ice cubes (9 at a time) quickly.
A little noisy, just like an internal ice maker in a lower-end refrigerator. Similar compressor sounds to a minifridge, but with falling ice cubes.  Agree it works better with cooler water. If ice cubes are stored in a freezer,  be prepared to use an ice breaker!

Update: 1 year later.  So going strong.
