Product review (5 stars): Totally worth it!  It worked!
Our water line stopped working about 4 months ago.  (Ice dispenser still working) After a few weeks, I went on YouTube and watched a video on how to clear the line. I used the hairdryer trick and unclogged the line....for about 4 hours.  Tried it again. No luck.  Finally, after searching for a service repair company, I happened to stumble upon this beauty of a tool.  Our 11 year old son is the one who used it and it worked!  We must have had a lot of ice in the line..... We had to use it 3 times in the first 24 hours, but it's been dispensing water now for a week straight!  We were so happy to finally be rid of gallon water jugs on the counter.  We use our water line a LOT...  Thank you. It worked wonderfully!
