Decent room divider for a good price.
Size: 4 Panels, Color: Grey
Honestly I'm pretty happy with the product for the price paid. The instructions were relatively easy to figure out and I put it together myself in an afternoon. Looks good for how cheap it was, and does exactly what I wanted. Double check your measurements before buying, but this worked out great for me.

Great solution if you need some privacy!
Size: 6 Panels, Color: Beige
I had my family and relatives came over last holiday and I needed to provide a make shift rooms for them. I have a finished basement. I purchased 2 sets of VEVOR 6 Panel Room Divider and solved my problem.
The VEVOR 6 Panel Room Divider is a practical and affordable way to create privacy in any space. It’s easy to set up and the folding design makes it simple to adjust or store when not in use. The panels are lightweight but still feel sturdy enough. Assembly needs some extra patience
Overall, a great value option for flexible and convenient room separation. Highly recommended.

Super Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
While not elegant, these dividers are study, stable, and made of surprisingly high-quality materials for the price. The fabric has a heavy-duty feel and stretches nice and tight with no need to individually Velcro the top and bottom in place as compared to other options. That makes screwing-in one bolt per panel section a bit of a challenge that is best done with two people. However, the results are worth the effort. Otherwise, super quick and simple assembly. The included hex wrench works OK. However, using a 5/32nd inch (4 mm) hex bit in a manual or electric screwdriver dramatically speeds assembly and disassembly. Everything fits nice and neatly back into the divider's shipping box provided one carefully preserves its packing materials and notes how the box was originally packed. Our organization ordered 8 additional 4 panel sets after initial testing of one set of panels indicated that they were an extremely cost-effective alternative to renting "pipe and drape" to support displaying and dividing artwork. We plan to use rubber backed pushpins (also available via Amazon) to affix items to the dividers as needed.

Great Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
These are great value and ideal for a divider that needs to be moved or maneuvered a small distance on a regular basis. Assembly is quick with a drill (don't over-tighten). Fabric seems of good quality and the unit seems sturdy expecially when linked together.
