We had the window screen installed in our living room because we were impressed by the advertisement that says it has a superior stainless steel mesh and excellent grip protection. The kids' playroom is at the second floor so they like horsing around in there. The window screen they installed promised to withstand tension and a lot of weight. We obviously cant keep the windows open all the time esp if there are kids and we dont wanna close it to hide the great view outside. So far, it looks pretty tight and really strong/ durable to me. We'll see what happens then!
