It’s a hard no from me
Color: Black, Size: Upgraded Base-1 Panel
I ordered two of these black, single screen panels several months ago. I ordered an additional four I needed a few days ago so I would have the total of 6 that I ended up needing. I did so by clicking on my past order (2 screens) item page and simply placed my recent order for 4 more. Two of the six screens have bolts that don’t fully screw down, such that one of each panel’s four points where the screen attaches to the two legs isn’t fully screwed down and flush. As a result, the screen doesn’t stay entirely vertical -It’s warped askew. Also, 3 of the six screens are different heights than the other 3. It’s clear to me that this company has ZERO QUALITY CONTROL, as there’s not anything that is even adjustable on these screens that leaves room for user error. Additionally, there are four black rubber circles that come in the “parts/screws” bag that don’t have corresponding installation instructions in the instruction manual. Just spend a little more and go with a better quality product somewhere else.
