Not good for putting away daily
Color: Grey
This product may work of you are doing a full install, but is terrible for putting up and taking down daily. I have only had it 2 months and it is falling apart and will not stand straight.

Privacy at ease!
Color: Black, Color: Black
This is exactly what we needed for our large house and bedroom sharing with the kids. People need privacy and this can be tucked away when it isn't being used. Perfect!

Easy to put together
Color: Black, Color: Black
I was pleasantly surprised by how well this room divider is designed. The engineering behind it is actually pretty thoughtful. All the pieces line up exactly where you expect them to, and the connectors make assembly almost foolproof. I had it put together in just a few minutes without any frustration or extra tools. The fabric panels look clean and modern, and the whole unit is surprisingly lightweight. That makes it easy to move around if you want to reconfigure a room or create a quick private space. Even though it’s light, it still feels stable once it’s assembled. Overall it’s a simple product done right: easy to assemble, easy to move, and it does exactly what it’s supposed to do. I’d definitely buy it again.

Light weight and large privacy screen
Color: Black, Color: Black
The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.
