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.

Fantastic for furniture making

Frankly, I didn't know what to expect... But these turned out to be exactly what I was looking and hoping for. These table legs were so easy to assemble. They come with adjustable feet so you can have a level table no matter your tabletop shape or floor situation. Assembly is done with a simple Allen key. Printed instructions are included with simple diagrams that are so easy to follow. Also, the seller provided all the hardware needed and more! They provided multiple black screws of different sizes that fit through the top holes of the legs, making it so easy to screw the leg base into the table top (use an electric drill with a Philips head for that). I had zero issues with any of the hardware provided. The base has a nice smooth black powder coat application on the metal. Shipping was so quick too. Seriously, if you are looking for a low cost, easy to assemble, good looking, and adjustable end table base, get this. I ended up making plant stands with these using some tree slices I had as you can see in my photo. 10/10 highly recommend.
