Product review (1 stars): Keep looking; this product does not meet claims.
From the very start, this product was extremely slow to make ice.  Expect to wait at least 1.5 to 2 hours for the first ice drop after filling the unit with cold tap water.

Things that are different from product claims:
***  It definitely never made ice in 30 minutes; average for each ice drop is around an hour.
***  The product picture which shows it full of ice is extremely deceptive; the unit shuts off after the tiny ice holder fills (it can never actually get full of ice as pictured).
***  The product holds 1.5L of water, not 15L.
***  Convenient view window -- try as you might, you cannot see the ice through this window.
***  Claim - Produces up to 25 to 35 pounds of ice per 24-hour period.  Let's do the math.  1L of water weighs about 2.2 pounds.  It takes this unit around 5 hours to turn 1L of water into ice at the rate of 24 cubes every hour.  Let's give it the benefit of the doubt and say it can turn 5L of water into ice in a 24-hour period.  That means it is creating 12 pounds of ice per 24-hour period.  To keep the ice from melting, you need to remove the ice as it is made and place in it a freezer.  Of course, you aren't going to do that overnight, so you can count on 25-50% of the ice made in a 24-hour period melting before you have the chance to use it.  That means we're now down to 6-9 pounds of ice per 24-hour period.

We kept the unit in a temperature-controlled room that is right square in the middle of the temperature range per the instruction manual.  We cleaned the unit frequently, per instructions in the manual.  Less than two months after purchase, the unit stopped producing ice altogether (it ran, but the water did not chill).  We are still awaiting a response from the company about repairing the device.
