Product review (5 stars): Worked perfectly
Have to say this worked like a charm.  My water dispenser in my fridge just stopped working one day.  I knew it was still getting water since the ice maker was still producing ice so the most logical thing was that the line to the water dispenser had frozen.  After looking for a solution I found a link for this product.  I just received it today and it worked perfectly.  Microwaved a cup of water for 30 seconds and filled up the plunger.  Pushed the hose into the water dispenser tube as far as it would go and pushed the warm water into the line.  It took 2 tries, but it cleared out the piece of ice that was blocking the line.  So happy my water dispenser is working again and it really only took me a couple of minutes to get it fixed.
