Easy to put together
Size: 16 x 18 Inch
Great legs and look great with the table, however, the legs connect to a peak and is not level. A friend made me some spacers on his 3d printer so I could use them.

It high quality but usable.
Size: 16 x 18 Inch, Size: 16 x 18 Inch
Kind of poor quality. The 4 way connectors do not set level to each other and the 3/16” Allen screws strip out very easily. I wouldn’t buy again.
