They're a unique design, definitely would be nice to have at a home table. And they're made by a good manufacturer, which is great news.
In the beginning my ball buying journey last year, I didn't originally know about the ball quality topic very well besides not wanting "garbage bin" balls. This is also how I came to even own the "Tiffany" ball set and the "Louis Vuitton" ball set knockoffs. The Tiffany ones aren't a complicated design, so they're "fine", just don't feel very nice and are a little "matte" on the finish. The LV ones suck; gaps in the resin, sunken parts, and uncentered and inconsistent execution. I didn't have a good understanding of this until I opened the Diamond by Cosmos balls and their phenolic resin and vitrification layer were amazing.
So, the fact that these are a nice set, made by Dynasphere, and are also phenolic resin are all big pluses. The price though seems like $450/set?
