Product review (5 stars): Works very well.
It worked great for us.  It had every attachment and piece that we needed.  The directions were way more detailed than I expected.  At first I didn't think we would use the longer skinny brush that came with it, but that one turned out to be very helpful in getting the lint out from inside the actual dryer.
We now have a dryer that works well again and dries clothes quickly just like it used to do.  We'll keep this around to clean things out again in a few years.
