Product review (5 stars): BEST PRODUCT EVER!
THIS IS SO COOL! Easy 30 min install max. Just the best idea ever. Well designed, well engineered. There's a beveled flange to be sure everything lines up with the coupling. No more reaching behind the dryer, trying to line up ductwork--or worse using a mile of flexible hose. This is SO EASY and so well thought out. It's almost magic...

Worth every penny. Thanks MagVent--where have you been for the past 50 years?
