For the price, this is exactly what we needed.  However, it was sewn a little wonky and had some gaps.  It was easy to install with sticky velcro strips.  The strips do come off in the hot Texas heat, so I recommend using the tacks that were included if you live in a hot climate.  The magnets were offset but still functional.  I loved how my dog was easily able to walk through and the magnet fasteners quickly shut out the mosquitos and flies!  The material is not very durable but for the price, this screen is a good buy.
