This product would be great if it fit. I have tried both size options available but neither fit - one was too big and the other too small. I'd go with the larger size but I have stucco walls that are pretty difficult to mount to, and velcro wouldn't stand a chance. I gave it 4 stars because It does seem to be made up of good quality material and I'm sure I would love it if only they offered an in-between size option. Also, this brand is superior to some of the others I've tried. Other brands have fewer magnets down the center seam, leaving large gaps for critters to invite themselves in. No bueno!
Why couldn't insects be more like vampires? They wouldn't be able to get into your home unless invited!
