Product review (1 stars): Doesn't work - not worth it
We ordered the vent booster to fix a problem we were having due to our dryer vent path being longer than usual and not functioning as well as we believed it should.  Clothes were taking too long to dry and got musty smelling easily.  We spent a day installing the booster. I seemed to work when blowing air into the probe before installation, but when installed as directed with the probe being perpendicular to the vent, it only worked hit or miss and did not seem to help the problem at all. We opted to redirect the vent to a path with less curves and used a smooth metal vent system instead and now clothes dry within 30 to 40 minutes. We were not refunded for our shipping and had to pay to ship the very heavy merchandise back to the vendor.  Overall this cost us about $30.00 and 2 days work to find out this product STINKS!  I wouldn't recommend it at all.  Find another solution.
