Product review (1 stars): Sucks
Do not, I repeat, do not purchase from this company.  I would have done better to wrap a piece of aluminum foil around a card board tube, not a week after installing this vent did it spring a leak.  I'll go to Lowe's and pick up something more suitable.  The kicker is that I had to pay almost six dollars for a sixty cent vent, I learned my lesson, the fasteners don't even have enough tension in them to hold the thing secure.  I was suspicious when I saw the price, I know you get what you pay for, well this company will NEVER, EVER make another sell to me, or anyone I know, quiet as kept, there is no way they can even make this right, I know personally the lack of quality of their products, cheap tin foil, no more, no less.
