Product review (3 stars): Very involved, instructions not complete
So get ready to take the dryer apart - the drum comes out, etc.  It's quite involved considering what a simple procedure it is to change a jet.  They buried the jet under the drum, etc.  The step-by-step instructions are fine until the very end when they kind of leave you hanging and don't tell you to actually replace the 2nd jet.  Customer service knew nothing (they emailed me another copy of the instructions).
It works, but you have to take a leap of faith with the last jet and be prepared for a 2 hour job or so... it's kind of a drag.
