Product review (5 stars): Loved it?  Well, I at least appreciate it alot.
My 18 year old dryer had stopped drying properly.  I went online and looked for possible solutions.  This was the cheapest thing to try first.  Installation was very simple and it took care of the problem.  I guess you're supposed to clean the back of the dryer about every 3-6 months.  Yeah.  Like that's gonna happen.  18 year old dryer and I think it's been cleaned twice now.  Once was because something rolled into the lint trap when I was emptying it.  I'm so glad I bought a Kenmore when the name still meant something.
