Product review (4 stars): it does a good job on making them
I only used this for 2 weeks.  I wish it kept the ice frozen, but I understand why it doesn't.  Most compact ice makers don't keep the ice frozen.
It did the job.  It makes ice fairly quickly.  The first batch of ice (8-10 ice cubes from what I remember) doesn't completely freeze so their a bit small.  After that though, it does a good job on making them.
Once it runs out of water, it stops and flashes a light warning you to put more water in it.  It seems to still have quite a bit of water in it still though.  I'm sure there's a reason why they stop it early though, so who cares.  If you're looking for a little bit of ice occasionally, this works fine.
