They are stock on my TNT6. They are very easy to level, and well constructed. I believe they are using the same balls as the Gingko, and I believe I heard somewhere that they worked with VPI on tioushe design. (Ginkgo has been selling dustcovers for various VPIs for years)
Can't say much about about A/B vs older feet, but I'm happy w/them. Cheers,
