Product review (5 stars): Unbelievably simple concept, but exceptionally effective!!
OMG, the concept behind this is so ridiculously simple, but the tool (if you can really call it that) is very effective.

I have a GE side by side refrigerator that has the notorious problem of the water line freezing.  Even with a water line heater installed it would periodically freeze, particularly in the winter when the water is colder.  To unfreeze it, I would spend 15 minutes (minimum) running a hair dryer all around the water dispenser in the freezer.

The line was frozen when I came home from work today & thankfully the Ice Surrender was in my mailbox.  Followed the very simple instructions and had the water line defrosted in less than 5 minutes.
