This is a cheap solution to a major pain of a problem.  I used to have to take an hour out fo my day, empty the freezer, and use a hair drier to unfreeze the line.  This kit is easy enough that now I just let my 7 year old fix the problem in 5 minutes and he tells me when it's done.

Might be the smartest little invention and best cheap purchase I've ever made.
