Product review (5 stars): Works great!
I have had a blocked dryer vent for a long time, and had been venting the dryer to a small, water filled plastic box which I found at a big box store. Then I found this and what a find. This works exactly as advertised. My son was able to clear the ductwork in about 45 minutes from start to finish. The shop vac was about 1/3 full of dryer "fuzz". The dryer works great now and I'm not having to fight the heat from the dryer via a ceiling exhaust fan. Would highly recommend!
