Quick search couldnt fin anything. Login in to record power and look at a manual - will usually list where its mfd. Depends on your definition of quality. At the end of the day my measure is value - cost vs competition, feature comparison, mfg tolerances (some matter some dont), and does the higher priced item provide any value to me, more precision or accuracy, longer life, easier to use, etc. Ive seen some reviews of their chucks. Some differences from the technatool line (record was selling nova rebranded - not sure just what the situation is with the new ones). The biggest difference I see is cw closing of the jaws, which nova has also changed now. Dont see value in the beefier jaw slides, the nova’s work fine. Jaws are the same for both. For the $ difference I think nova would be my pick.
