So, this does work amazingly well, very easy to use for cleaning the dryer vent, seriously the entire process of cleaning the vent took only about 10-15 minutes. The biggest complaint that I have is that if you are using the drill attachment (and you will want to use the drill attachment, trust me, it would have taken so much longer doing it without it), the rods get so tightly attached that you will need to use plyers to unthread them to disassemble. Not really that big of a deal, but if you don't have two sets of plyers available to use, you are going to find yourself stuck with, best case scenario, a long rod that is difficult to store when you are done, worst case scenario unable to add in extra pieces for a longer rod to reach all the way through the vent. Also, the instructions say to wear eye protection and a respirator, it should also advise you to wear something to cover your hair if you have a dryer vent that is above the level of your head (dryer lint is very hard to wash out of hair, learned that the hard way).
