Clean The Lint Out

LOL..I actually think I really want one of these. The lint b gone is one of nifty little tools every drier needs. I see the amount of lint I get from the lint trap, so I can only imagine how much gets through into the drier vents. I guess with the rising energy costs it may be worth the small investment. My drier is a few years old and I have never cleaned anything except the lint trap. If you have one let me know wjat you think.
