Product review (5 stars): Works like a charm!
Actually works! I was shoving weed wacker wire up the water dispenser of my fridge when the line would freeze. I simply fill a small cup of hot water and shove it up in the tube... works every time. Probably should mention to look at replacing your fridge filter if the water line keeps freezing. In my case, the filter was old and causing the water to slow flow which allowed for air and freezing. After changing the filter, I barely use this anymore.
