Product review (4 stars): Basically works but must be aware of its limitations.
We have had this for 2 weeks.  Generally happy with it now.  However the claim of ice in 20 minutes after start-up is very misleading.  From a cold start ours took 2+ hrs.  What is happening is the recirculating water has to cool off enough for ice to fully form in the tray.  Our room temp is high 70s currently.  Water is triple-filtered tap water, not particularly cold.
After the unit has been running for awhile and making ice, the recirculating water reaches a low enough temperature that the ice forms readily.  So I think the unit is a bit under-powered.  If one were to attempt harvesting lots of ice from this machine, it would be an all-day project, because constantly adding room temperature water will slow it down.
Another strange attribute of this unit is that it transfers a dose of water from the main reservoir to the recirculating water at the start of every cycle, even when additional water is not needed.  The effect is to partially fill up the ice basket with liquid water.  So, you have to watch the water level and do not keep re-filling unless the water level under the ice basket is getting low.
Hopefully these comments are helpful.  I was getting ready to send it back after no ice production within 1st hour.
