Product review (5 stars): Not only was it super easy to accomplish
Our dryer vent hadn't been cleaned for 8 years.  I was about to call a company to come in and clean the vent, but I decided to see if there was a DIY kit.  Sure enough, I came across this kit.  I was a bit hesitant considering the low price... you get a lot for the money.  Since it was Prime, I decided to give it a try.  It arrived in a couple of days and just cleaned the vent.  WOW!!!  Not only was it super easy to accomplish, but I was amazed at the results.  Further, I did a load of laundry immediately after and I found a 20 to 30 minute dry time savings per load!  This thing will more than pay for itself with the electricity savings!  I plan to clean my vents on a routine basis!  Our vent goes through the roof, so the 12' extension kit was needed.
