Product review (5 stars): Works great but takes some time to set up
This works really well, although you definitely need to seal the seams with foil tape and it takes some thinking to figure out the size and position. I needed to cut mine down severely but with tinsnips and patience it wasn't too difficult to get a perfect, custom fit. This replaces (or should) the classic dryer vent hose. The position of my dryer vent and a badly placed gas supply line relative to the dryer made it so I couldn't get the dryer back as far as possible but the connections and better design of this than a normal dryer hose were totally worth it
