Good to keep my room cool or to let in some fresh air during the hot late spring and summers. I never really saw the need for window screens until I got kittens... living on the first story as I do, I had to invest in screens the second I brought my two 9 week old buggers home. I did a lot of research and thought I'd need something with really strong, metal wiring to keep them from fighting through, but as it turns out? These are perfectly fine.I got them as a temporary solution as I was trying to figure out how to build and proper install more permanent window screens. My kittens have respected these screens since the start though, and they generally have no desire to tear through or claw at them. I have really sweet kittens (now almost cats. I've had them over half a year now with these screens). I'd get one of these screens and test them with a single window whilst keeping an eye on your cat to see if they'll behave around it. I'm perfectly confident in my ability to leave my kittens with these in my open windows for hours.For installation, easy. Pull these open to the length of your windows, fit them behind the outer grooves on the sides of the window, pull window down to snugly hold the screen in place. My window is much longer than the shortest screen, but I just bought that and carefully snapped out the black pieces that hold the screens in place, reconfigured the screens to open the other way round, then snapped them into place again. Just be careful not to pull on them too hard. I reckon a little too much force would break them.Perfect value for me. I get to have fresh air and breeze, my kittens get to look out the (usually closed and translucent) windows and enjoy the view, and there are no kittens falling out my window. Cool and pretty decently sturdy stuff for cheap. Don't think it gets better than these.

Very good window screens — convenient size, with both wide and narrow options. They’re easy to expand and very user-friendly.

This screens are pretty well made and a great size for my windows. The window frames don’t have a track to hold a screen so the weight of the window keeps the screen in place. It’s good enough to add ventilation but not secure in a rough window or if a pet or child gets rambunctious.

Well made

Simple, clean lines, no unnecessary gadgetry. It just does what it's supposed to and does it well for the money. It's not the thickest best screen or frame but for the money compared to others on Amazon, it lets in the fresh air, keeps out the bugs and doesn't rattle or move about when the window is pulled down onto it to hold it steady. My only suggestion would be to add a little knob or handle on one of the sides so it doesn't fall out onto the ground when you push the window back up to disengage it. Very minor but would be helpful. I like this very much and glad I bought it. Remember there is nothing but the window sandwiching it onto the sill to hold it in place so it would not be a good line if defence against a child or pet.

Great

The fabric had an extra tread in the center of one of the panels. I noticed the obvious visual defect before I took it out of the box. Any assembler, or quality control inspector, or packaging person should have noticed the defect immediately and set this screen aside.The sealing strips were cut short before assembly leaving gaps at the corners. Another obvious visual (and functional) defect that should have been detected if quality is important to this manufacturer and distributor.The design is good. The plastic parts are fair. The frame is acceptable. The screen fabric would be acceptable if not for the visual defect. The workmanship and quality control is poor. Packaging was adequate.

The screen fits the area perfectly, but it can't bent and torn. Maybe a little thick.
