Product review (5 stars): OMG, I wouldn't have believed it...
OMG, I wouldn't have believed it if I didn't see it. One day, I was smoking on my sister's front porch, right next to where her dryer vent came from the basement. I lifted up the little flap, and there was MAYBE a half inch diameter of clearance for exhaust, TOTAL fire hazard. As soon as I got this, I went over there, unhooked all the required hoses, & followed all the directions (Very easy setup & instructions, nice additions...YOU NEED A DRILL!)) The was maybe less than 6 feet from the front of the house to inside where the dryer hose was, and it it FILLED up my ShopVac! I couldn't believe it. It made me feel so good, because of my nephew living there as well, I never really realized how bad it can get and how dangerous it really can be. GREAT PURCHASE! Also gives you great piece of mind, for a rather modest price point too...totally worth it!
