Quite good!
Quite a solid set of legs. It little flimsier than I had hoped for but we are not moving the table we built around much. The wheels are also quite small. I would purchase again though!

An average table support.
These table legs are made of "jointed", threaded, 3/4inch steel pipes and it is imperative that they are assembled correctly and evenly; if not, the table will be wobbly and unstable. Need to ensure that the joints are fully tight. The assembly instructions are vague, so you may face some frustration during assembly if you're not too mechanically inclined. It is possible to modify the design of the legs to meet your specific needs, but you may need to purchase additional 3/4 inch piping and couplings at your local plumbing store. Good luck!
