I live on a higher floor and need a sturdy screen to keep my cat, who's nickname is Deathwish, from attempting flight. I've bought other adjustable screens that were cheaper, but I rarely used them because they were flimsy and frustrating to use. These are sturdy, slide easily, lock in firmly, and are resistant to Deathwish's best headbutts. I'm thoroughly enjoying the spring weather without worrying about the bad cat.

These are well built and easy to use. I wish I could afford the regular ones. These do not seal perfectly and are touchy to adjust each time I put them in. Nevertheless with a 3 story house and no screens, I am pleased. They arrived quickly. Good service.
