Product review (5 stars): I LOVE it: the thing is HUGE!
I have had a number of this type of  ice makers and I love this one.  It is huge!  I bought one like this a number of years ago and paid over $200 for it out of Sky Mall which is gone now.  We use them in our RV, so it is going 24 hours a day most of the time.  It eventually failed and any replacement I purchased was half the size [which was good for the shelf] but only made half the ice.
The ice isn't crystal clear but is below 32 F degrees and keeps everything in the standby cooler just fine.
Campgrounds are starting to charge $2 for 8 pound bags of ice so it doesn't take long to pay for the machine.  All you need is 110 volts and clean water to make 50 pounds of ice a day.  We take care to empty, dry and secure the machine between stops.
We use the large setting exclusively and we always have ice.
