Product review (5 stars): Still working & dropping cubes for the last two months.
Easy installation. Make sure to remove the water filler tube from the back of the unit.  Run hot water incase your tube was iced solid,  mine was.  I had to slightly adjust the water pressure down using the wall valve.  Do not expect instant results, sometimes it takes the built in temperature modulater some hours to get repetitive.  Do it yourself, learn and save some money!
