Product review (5 stars): Good Old American Ingenuity!!
The problem of a frozen water line on my GE fridge has happened many times over the years.  Like so many of the other reviewers, I used hair dryers or shut off the power in order to unfreeze the line.  But in the summer, there is no place to put the frozen food during this time.
I had my doubts, but the first time I used the Ice Surrender, the water line started flowing in less than a minute!
5 Stars for good old American Ingenuity!!
