Product review (4 stars): Works well
This works fine but the one it replaced was a little nicer because it was designed to be attached to something stationary like a stud.  So I drilled small holes in the plastic and attached it to the wall where the other one was. That keeps the dryer vent hose from moving and maybe coming loose. It does seem to be constructed very well but there is one drawback. My dryer vent hose is not plastic so the plastic clamps did not work. I used metal clamps that can be screwed tight. Otherwise, I'm satisfied with the purchase.
