Product review (5 stars): Works great for us
My wife loves ice.  In her world, it's #1-Kid #2-Ice #3-Dogs #4-Running and #5-Husband.  Or maybe I'm lower, not exactly sure.  Hand puppets probably are above me.  But regardless, I want to make her happy.  And she LOVES ice.

So we have the counter-depth stainless steel front-ice-dispenser fridge in the kitchen, but the ice maker in that thing is just plain trouble.  I've fixed it about three times, and the last time I couldn't figure it out, so we called the appliance repair guy, who came out, said "Yeah, these ice makers in the doors of refrigerators are always unreliable.  I'd never buy one..."  and then told us it would be $300 for the controller board, plus another $200 for the other controller board, plus $200 labor or some crazy amount but - wife loves ice - so I said go for it.  Well, turns out that didn't work.  (He did take back all the parts so the charge was low).  But he's not sure, he thinks maybe the wire in the door is broken, need new freezer door for $1200.  But again, not sure.

So I'm looking for an ice machine.
Choice A: Counter-top?  Really?  Add water each time?  No thanks.
Choice B:  Professional under-counter?  Sounds good, but $2000 for the reliable one, plus install, which I could probably do, but have to find a cabinet to remove and then fill in what's left (best space was a 27" cabinet, but we'd lose the cabinet and the drawer and how can we find a 12" cabinet that will match the ones next to it?)
Choice C: These type of things.  This type is so odd - I mean just a regular cheapy-joe ice-maker in it's own little freezer?  It just seemed to amateurish to even consider.  But if A doesn't work, and B doesn't work - let's take another look at C.

Anyway, we tried it and so far it's solved the problem.  It doesn't really fit "under-counter" very well, since it's not as tall as a standard kitchen cabinet, and it's not short enough to fit where the doors of the cabinet were (i.e. I thought maybe I could leave the cabinet and the drawer and just put it where the door was.)  But in our house it just so happened that it fit on the countertop in the corner of the den which used to be an old wet-bar.  The counter is regular height like a kitchen counter, but the wall cabinets are smaller and higher.  We had taken out the sink years ago, but there was a water line nearby, so it was easy to tap into that, so I just stuck it on top of the counter, plugged it in, ran the water line from basement through bottom cab, behind wall and into back of this unit.  It came with a polyethylene tube but I'm pretty sure code in our city doesn't allow that to go through walls, so I used a flexible stainless steel supply line (well, actually I don't think that is allowed either, but it does seem sturdy and reduces the number of junctions and it eliminates those darned copper compression fittings, it has stainless steel fittings with a rubber gasket at both ends.)  The hookup for water is exactly like the one on the back of almost every refrigerator in America with an ice-maker.  Leaks?  I think this would leak just as often as any other fridge would -- it can be very ugly if it leaks, so double check!

Anyway, after hooking the water up, I turned it on, and voila!  Ice!  Lots of ice - it fills up the container in about 12-15 hours.  It DOES make ice faster than the fridge - I assume it's because it is much colder inside the little guy?

It DOES run almost all the time, I am not happy about that, as it seems to be inefficient and wasting energy, and you can't control the temperature (maybe if I made it a bit less cold inside it would make ice slower but use less energy?)  The cabinet exterior feels colder than most standard freezers feel, not sure if the insulation is thinner or what.

Several reviewers talked about the NOISE - it reminds me of refrigerators from 10 years ago.  You can hear it, but I find it's fine.  Our TV is about 20 feet away, and no problems at all.

How long will it last?  Can't say.  Overall, it reminds me of the quality and size of those college-dorm refrigerators so I bet it will last 2-4 years, but who knows....

But MOST IMPORTANTLY:  Wife happy.  Life happy.  She is generally a recycler, turn heat offer, save energy person, but when it comes to ice, she is fine with this thing.  Plus, if we get the kitchen refrigerator ice maker fixed, it will be easy to just unplug this, patch the water-line hole, and it's done.  Or get the kitchen one fixed and keep this one for parties, future break-downs, etc.  OR... maybe buy a big boat and then I would have this to put on it - it seems a lot of people buy it for their boat....
