Product review (5 stars): Stellar performance from a dryer vent?  Believe it!
I'm very pleased with this vent.  Never knew just how much of an improvement it would be.  Easy to install on wall mount.  Weatherproof & sturdy.  Don't fail to paint it (rattle - can) before installation to prevent sun rot.  Easy to clean & significantly reduces back pressure as well as draft to exterior of home.  I'm sold on quality & performance.  Well worth the purchase.
