Product review (5 stars): It worked and saved me serious money
When our dryer was literally taking 1 to 2 hours to cycle through to dry our clothes, I called in a repairman, who told me there was nothing wrong with the dryer, but that my dryer vent hose was most likely clogged. Since the hose runs about twenty feet under the house to the outside vent, I wasn't looking forward to shimmying under (God knows what's under there) to clean it out. When I called around to see how much it would cost to have it done commercially, I was getting quotes of about $200 or so for a hose that long. As if.

I researched online and found this dryer vent cleaning system. I didn't realize that dryer lint buildup is the number 2 cause of fires in the U.S. (DRYER LINT. THE SILENT KILLER) Anyway, I bought it along with the extension rods (for about $40) and after about 15 minutes had the hose cleaned out and a dryer that runs properly. I saved over $150, didn't have to climb under the house myself and now have it for future cleanings. Look, I'm the anti-handyman, but this was simple enough for me not even to screw it up. You should have a shop vac for the process (I borrowed one), although it does have a way to use your dryer's blower to help clean out your vent (I didn't try that one).

Overall, really satisfied with this product.
