Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design.
The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider.
I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc.
They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places.
But they wqould work especially well if you were not constantly moving them as we do.
They are a bit of a pain to assemble.
