Product review (5 stars): it worked like a charm
I could not get a company to provide the service of cleaning my ducts. Go figure in today's competitive market a company failed to show up on three occasions. Found this product and wow, you need an assistant as the process takes two, it worked like a charm. I filled a Wet/Dry Vac in no time and imagined that if there had been a spark we'd have been torched. This product gives peace of mind, is easy to use and saves you a ton of money even on one cleaning and yet you can use for many years.
