A new version of SolidSlime'S table tennis adapter has been released. Some pro players said the old one had - under special cirucmstances - tracking issues, but their needs are way higher than my low amateur orbit, I did not notice it. I am very happy with my version 1 of it.
Its also cheap, in price, not in quality.
