Good and attractive with a few finish issues.
Style: Zig Zag, Size: 28 inch
These are attractive and functional and work well. Some of the welds were not as precise as I would have liked, and a few places (not conspicuous) are missing a little of the finish, but overall they do what they're supposed to do. I used them with a butcherblock counter top to create a desk for my office.

Very versatile table for many uses.
Style: Rectangular, Size: 28 inch
These legs work great for replacing a free standing rv dinette by reusing the table top . We didn’t need a table that converted to a bed. Nice fit and finish and great quality.

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.

Pretty good, take your time and install it well
Size: side table leg
Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced
