Product review (4 stars): It works for me
The unit definitely serves its purpose.  If I had a basis for comparison, I might take away a star or add a star.  I needed a portable ice maker for my seasonal campsite, this one was the right price and qualified for "Prime" shipping.  It claimed to produce 32 lbs. of ice in 24 hours and it seems to do that...we don't weigh it, but we have plenty of ice whenever we need it.  The first batch is available in about 15 minutes.  That batch is weak, but by the third or fourth, it's as good as anything from a freezer's ice maker.  The only "problem" is that you need to keep it going....empty ice before it reads "icefull," and add water before it reads "deficient."  Both will cause it to stop making ice and sometimes we've had to unplug it to reset it.  A power switch would be nice.  So, someone needs to be in charge of the emptying and filling.  It's quiet.  You can choose from three different size cubes.  It makes lots of nice ice cubes...I don't know what more to say.  I hope this is helpful.
