Product review (5 stars): The dryer has never worked this good since I've rented my place
I'm surprised, actually, this thing is way more flexible than I thought it was going to be. I don't think my dryer vent line has ever been cleaned. It encountered quite a bit if resistance due to the build up, however, it cleaned the line very quickly and effectively. The only drawback is 12 feet isn't quite enough, going thru both directions there was still a few feet that it couldent reach. That's when a leaf blower and a long sock (to seal the exhaust port in the wall to the leaf blower) came in handy, whatever was left in the line was blown out with that. The dryer has never worked this good since I've rented my place.
