Product review (5 stars): Buy it, works very well.
Yes it works, I purchased this and the extension kit. Our house is 17 years old and it has an all metal vent pipe with a turn or two in it. My wife has been complaining for several years now that the dryer was not drying very well. I just kept telling her she was nuts... I have also had to replace my heating element twice in the last three years, I chalked that up to her doing 10 loads of laundry a week when I could do the same amount of laundry in 3. Well just look at the picture, I had a 5 gallon bucket full of lint stuck in the pipe. I have since apologized to my wife for telling her she was nuts...at least for this one particular circumstance. ***Purchase a dust mask, it is a very dusty project.
