The legs are solid enough, and the height addition was welcome by the players. But the finishing of the legs leaves something to be desired. There are lots of little mistakes.
Looks like some separation of the stain and gloss. (Paint?)
Dried drips. (Bad picture)
Drips and bare spots
Overall I'm happy with the product. These are the kinds of issues only the builder/owner would notice. I think they're priced maybe just a little bit high (299 plus shipping), given the issues outlined here.
I have these same X legs on my BBO table. I noticed similar issues with the finishing, but not quite as bad as these. Overall, I really like the table though, and you'd never notice the flaws unless you were inspecting them.
