Review on 4-inch Deflecto Dryer Vent, Galvanized Vent Hood with Wide Mouth Design, Silver Finish (GVH4NR) by Brad Davis

Advantages: One-piece construction so the transwall tube does not detach from the outer ventilation hood. The previous contender (bought from Ace Hardware) was so flimsy that it fell apart despite numerous "repairs" with superglue and duct tape. Cons: This thing is made from very thin sheet metal and has very sharp edges. No attempt was made to use the bevel on the edges which would tear the aluminum foil on the air hose. Again, adhesive tape was needed to set the standard for low-cost manufacturing. Is it really that difficult these days to produce quality items without sacrificing a reasonable profit margin?
