Product review (5 stars): Works Awesome!
My dryer was taking more than 90 minutes to dry a load of laundry.  I did a little research and found that it was probably caused by a clogged dryer ducts.  I have owned my home for 8 years and never cleaned the ducts before.  I called a few places and they wanted over $100 for a professional to come out and clean the vents.  I decided to try to clean them myself and purchased the linteater. This thing worked awesome.  I think I had over 3 90 degree bends so I was a little worried how it was going to work thru the bends.  It worked just fine.  I recommend using a dust mask while your using this product.  The product is only comes with 12' of extensions and my ducts ended up longer.  I just went and cleaned the ducts from the other end also.  I ended up filling up a 12 gallon shop vac with lint that was stuck in my dryer duct.  After all the lint was loose in the duct work, I couldn't get all of it out with the shop vac so I used a leaf blower to clear the rest out.  I'm so happy with the way everything turned out.  Now it only takes 40-50 minutes to dry a heavy load of laundry.  I hate to think how much electricity and natural gas I was using with a clogged dryer duct.  I plan on using this thing every year.
