Product review (5 stars): Wish I had this 5 years ago
Have been clearly my frozen line for years with a coat hanger.  Had issue and had TWO GE certified repairmen to my home, both said they could not clear the line and to install a new door.  One said $1200, another said $425.  Nice estimate GE.  Spotted this gem, took me 10 minutes and a towel and it was clear.

The directions say to heat the water for 30 seconds.  I heated my water for 90 seconds, and it took 4 or 5 times each time getting the tube in further.

Greatest thing ever.  Wish I had one 5 years ago.  It may have cost 30 cents to make, but it was worth WAY more than $12 to me.  Thanks!
