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.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.
