Perfect for working from home, creating privacy in my home office.
Color: Beige, Size: 4 Panel-67”
Easy to put together, took about 10 minutes by myself. I laid it on the ground folded (make sure the same direction for the brackets match). The only issue I had was one screw would simply not go into one side of the connectors. Using it as a background for my home office, so it won’t be moved often, so not super concerned, not enough to take the rest of it apart to see if I could fix the issue. Looks great, creates the privacy I needed for meetings.

Great for using behind me on Zoom calls
Color: Black, Size: 1 Large Panel
This works great as a place to put tapestries behind me when I'm on Zoom calls... much nicer than blurring out the background. Easy to put together, large, works great.
