Frost King AWS1837SP WB Marvin Adjustable Window Screen, 18in High x Fits 21-37in Wide

This Frost King adjustable window screen opens and closes easily and works as intended, and is reasonable in cost. Would purchase again.

A little awkward putting them in. But meets my needs

I love these for my windows that have ripped or torn screen. Keeps bugs out!

fit nice and easy into the window, 1,2,3 done.

The screens are not great quality. They are hard to adjust because they get stuck in position. When removing the tags the screens would pull right out of the frame. They aren't secured the way a screen is typically with a track and cord. They are just hooked on small notches cut into the metal frame. I don't recommend them if you have a dog or cat because they screens can very easily be dislodged. If you are just trying to let tje breeze in and keep the flies out then they are worth buying.
