This does a good job of keeping the cool air from our dryer from escaping all over the utility room. The velcro adhesive is very strong. I just found it a bit fiddly to get perfectly straight on the window frame. A solid product though.

A must-have for portable AC units
I was sceptical but this really works. My portable AC is much more efficient now. It was easy to fit on my sash window and the adhesive feels very strong. Has definately helped with the energy bills.

Holds up in the wind
I was worried a strong breeze would rip it off, but the adhesive has held firm through a couple of windy, rainy days. It's a solid product.
