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.

Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.
