Product review (5 stars): Works like a charm! Highly recommended.
It works like a charm!  We just moved into a home with a GE fridge that ALWAYS freezes up.  Every 6-8 hours it is frozen again.  We contemplated buying a heater for it which is an expensive fix, I decided to try this first.  It works great!  It takes about 3 syringes full of hot water to get the water line running again.  Our freeze is at the top, a few inches below the pipe that dispenses water, so a heater system would probably have been useless to us anyways.  This will be the perfect cheap solution until we decide to replace all our appliances, they work great aside from this freezing water issue.
