Product review (5 stars): Easy 15 minute project
It's exactly what I wanted.  An inexpensive way to divert hot and humid air back into my house.  I did buy metal hose clamps, but I used the white ties it came with to hang the unit from underneath my cabinets which are mounted over the dryer.  Just screwed some hooks into the bottom of the cabinet and hung it.  Easy 15 minute project. My house is old, dry, and drafty.  The more moisture I can get the better. The more heat I can retain, the better.
