Product review (4 stars): nice product but not as desribed
Product is a good idea for people who can not vent a dryer outdoors.
The ad for this kit is advertised  as having a 5 foot hose, but the hose that came with mine is only 3 1/2 feet long.
But it does work well and seems to work best with 1 1/2 inch of water.
My kit came with the much better metal spring tension clamps.
Update 11/17/2014- I have used this indoor dryer vent a couple of times now and I must say I am very happy with it, I have mine sitting on the floor between my washer and dryer, with 5-6 inches of clearance on each side and I have it 15-16 inches from my wall.
It does not blow lint on my floor, it puts out a little bit of warm air out into my house and the hint of the smell of fabric softener is pleasant.
I see no sweating or moisture buildup on my washer or dryer.
