Product review (1 stars): Poor Construction = Safety Hazard
I purchased this vent because it's smaller footprint would fit between the siding shingles of my home's exterior (other vents had too much overhang). Unfortunately, the craftsmanship of this product is EXTREMELY poor. It is worth noting that the actual materials are TOP NOTCH (durable plastic and a very rigid aluminum pipe), but the way it is put together renders it useless.

Firstly, any vent system that expels dirty air is supposed to fasten together with the smaller opening always inserting into a larger opening. If you have a large tube, which throttles down to a smaller tube you create a substantial lip, which not only obstructs air flow, but catches lint. This vent does just that.

Furthermore, the tail pipe doesn't seat properly onto the vent, leaving a good 1/4 gap on one side. Again, this will collect lint, and also creates a large air leak (problematic for colder climates). The gap basically defeats the entire purpose of having the damper flap.

Lastly, the tail pipe is fastened to the vent quite poorly by means of 2 large staples, which stick out into the interior of the vent pipe. Again, trapping lint and ultimately obstructing airflow.

Any one who has disassembled a dryer vent knows that even a properly installed one will eventually get dirty over time. This vent is SO poorly assembled that I can't imagine it lasting more than a year before it becomes so clogged that it becomes a true fire hazard.

Unless you're willing to cut, epoxy and retool this vent to suit your needs, I would stay away.
