Product review (4 stars): Excellent if you manage your own expectations.
I purchased this unit a couple of weeks ago.  It has been used almost continuously the whole time.  At home, we use it in our den as the fridge in the basement has no ice maker.  We have used it over the past week in the camper.  The size is great and the output is what we need.

We normally buy 1 to 2 bags of ice a day when camping.  This trip, we have bought none.  Don't expect this unit to provide instant output.  It is not your at home hotel ice maker.

I read a lot of the reviews before buying.  The quality of the ice is directly dependent on how cold the water reservoir/ice chamber is.  The first batch of ice after a water refill will be smaller, softer cubes.  As the water in the reservoir cools, the ice making cycle will become more efficient.

I experimented with recycling cold water out of the cooler to make ice.  The quality of the ice remained high on all batches.  When I fill it with tap water, the first batches are of lower quality.  The best solution is to "prime the system" by putting some of your ice into the reservoir when filling from the tap.

In order to produce a sufficient amount of ice for camping, the ice making process is continuous.  When hanging out, dump the ice hopper when the full red light comes on.  When leaving the camper or going to bed, dump the ice into the cooler and make sure the water reservoir is full.  You will have a full load when you return or wake up.

At home, the cycle is less intense.  Make ice when convenient, put it into freezer bags or an ice hopper and put it into the freezer.  Expect the cubes to freeze together, but it is easily broken up.

I am rating this a 4 for two reasons.  First, I don't know the longevity of the unit.  Second,  my gut feel is that a smart engineer could improve the efficiency of the ice making cycle through improved insulation of the ice chamber or extending a coil off of the compressor to cool the chamber.
