Product review (5 stars): Don't give up on that old dryer...
I was going to purchase this at Lowe's but it was much cheaper on Amazon. It arrived in 2 days.  The home we moved into had a washer and dryer included, but the previous owner was using the dryer with a torn lint screen.  The result was a completely clogged lint catcher in the front of the dryer and a very clogged lint pipe going outside.  I was able to use it to clean out the pipe that goes 10 feet up.  I didn't use the vacuum attachment.  I just had my vacuum ready.  Dryer works like new now!
