Product review (2 stars): The diverter does not seal tightly
It works but it's cheaply made. The handle that moves diverter falls off easily and needs to be glued on. The wire mesh is coarse. I used a small bungie cord and a piece of panty hose over the wire mesh to catch any lint. The worst thing is the diverter does not seal tightly. Even when set to direct all the hot air outdoors you can still feel a lot of hot air entering the living space. So it will make your home warmer in the summer as well. It needs a seal or a gasket to make it air tight. I would pay twice as much for one of these if it was well made.
