Quality control lacking
One tee conector was missing. Nothing avaliable locally that fits.

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Stacking shelves
These work perfectly, even in rooms with high ceilings. One thing I didn’t really see mentioned or highlighted anywhere is that they can be stacked. I decided to try it anyway, and it turned out awesome. I purchased two units and placed one on top of the other, which essentially created one tall shelf. It ended up being a great way to maximize vertical space and made the setup look much more custom and intentional
