Product review (2 stars): It will do....in short intervals!
I was a bit skeptical with ice maker initially.  Knox was not a known brand to me, but I needed a compact ice maker, which required less than 150W in power, only costs a nominal amount of money, and would ship to a military APO.  This Knox Ice Maker fit the bill

Good:
- It makes ice fast (as most compact ice makers do)
- The ice is hard/solid  Meaning that it is not very porousand that it is slow to melt and doesnt immediately water down your drink.

Bad:
-  Only lasted about 10 months (barely) of continuous use
-  Incredibly LOUD!  My house is approx. 2400 sq ft and I could hear the ice maker dropping ice while on my front porch.  We kept the ice maker on 24 hrs and it would often wake us up at night with the churning.  The ice dropping process sounds like we were disposing dead bodies, it was AWFUL!!!  And the fan for the ice making was quite noisy and distracting.  And the beeping!  OMG!!!  And as far as I could tell, you cannot turn it off. (or at least, we couldn't figure it out)

The ice maker that we initially had was an Igloo Ice103:  it lasted 14 months of continuous, much quieter, and more user friendly (it took me a while to figure out how to set the Knox Ice Maker to 24 hrs).However, the ice from the Igloo Ice Maker was not as solid and melted almost immediately regardless of the size of the ice or the temp of the drink.

So Id recommend this unit in short intervals, i.e. parties, camping trips, etc, but definitely not for continuous use. UNLESS, it is stored in the garage, basement, or laundry room (somewhere the noise won't matter).

I downgraded to 2-stars because it didn't last a year.  Otherwise I would have given it 3 stars. 1-year is the baseline for me because I don't really expect that these types of ice makers are meant for continuous use....AND it was only $100 (+/- a few dollars).
