Product review (3 stars): it sorta works
Its ok, the first time i used this product I did not get all the crap out of my ducts coz it wasn't sturdy enough and  just got stuck in a big pile of junk in the duct. I had to call a duct cleaner to get my ducts taken care off but hope that since doing so, it will be easy to keep the ducts clean with this tool from now on
