Product review (2 stars): Tube is too short
It comes with a roughly 2 foot long tube, but the line running through the freezer is about 4 or 5 feet long. Used it over and over again but could not clear the blockage. And I verified that it is a frozen line by disconnecting the tube at the bottom and verifying that water will come out if that line is bypassed. Just bought a 4 ft one that comes with a 5 ft steel cable. I suspect that will go a lot quicker. The instructions are mediocre too. The suggested time to microwave water does not leave it very hot. Also should instruct you to suck back out the water after it has cooled off before adding hot water again.
