Wouldn't do without it
So simple, so useful. I should probably have paid more attention to the instructions - after it was installed I realized I should have turned it 90 degrees . . . oh, well, it seems to be doing the job.

used for my clothes dryer
i have 2 dryers installed, and venting them out in summer and using the warmth in the winter.. this baffle fits perfectly with the flexible metalish ducking for dryer vernt.. i put it inline..works perfectly.. dryer produces enough air to open it, and works great with my second dryer working too.. even as a gasket inside for the baffell..not to be used for heating, fire, or direct burn.. the dryer vent is ok.. but i would not use this for anything hotter than i a dryer heat

One way vent
It’s been 2 months since installation. Works as expected. I don’t hear any flapping of the vent when the fan is turned on or off either.
