Product review (2 stars): Maybe mine was a bad one!
It was a simple plug in replacement for the one that died on my Whirlpool fridge. It works and continues to do so. It was also dirt cheap, which is my kind of price! I can't give it 5 stars as I haven't had it for long enough to test its' reliability, but I suspect it will be at least as good as the original.

Update: Not reliable at all! The timer that determines how long the water runs for failed, and my cubes all became joined together along with water overflowing onto the food below. I tried adjusting it but it made no difference.
