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.

Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.
