Product review (5 stars): Amazing tool
We just moved into a 40 year old home and noticed that our dryer was taking almost twice as long to dry clothes as in our much newer previous home. It finally dawned on me that the vents may be dirty so I bought this on a whim. It is extremely easy to use. I made the mistake on trying to remove the vent cap on the outside of the house and pulled out the first 6 feet for tube with it. The upshot was that I was able to do it in two sections and didn't need the extension kit as a result. I have one of those insanely-large shop vacs and it was about 1/2 full of lint when I was done. The dryer is much happier and I think that the reduction in drying time and corresponding drop in electric use will pay for this within the year. Don't have to worry about the house burning down from lint-balls either :)
