Product review (4 stars): Works great but the hose is too short
I bought this for my daughter, who moved into a townhouse with no outside vent for the dryer. My daughter's friend also surprised her with this vent kit. The one he purchased leaked. The one I purchased did not.

The hose for this is really too short so my daughter's friend bought a longer hose at the local hardware store. That allowed the vent to be wall-mounted, so it doesn't get kicked over.

My daughter has had no trouble with this vent system. It does a good job of trapping lint. She lives in an arid climate so the added humidity is actually a welcome feature. I am pleased with this product.

My daughter's friend either did or will return the one he bought, because it leaked.
