Product review (5 stars): Amazing!
I almost never write reviews, but had to this time.  I bought the lint lizard previously, and was very sleptical of this at first.  This product is amazing and you would not believe the amount of lint that came flying out of our dryer vent after this thing was shoved in there.  Very easy to use, but it did take two people, one to feed it in and one to operate the drill.

Worth every penny and saved us a $180 service call to have someone else clean the vent!  Pays for itself after one use.
