TechDAS Air Force III original vs Air Force III Premium & S

I saw someone mention that the original TechDAS AF-3 had some speed or reliability issues.  Does anyone know if this is true and if they made changes in the Premium or Premium S versions which improved reliability?  Thinking of purchasing a used AF-3 original.  

Thank you!


That's almost comical. A table that expensive...its only job is to rotate at a constant and reliable speed, and it has trouble doing that?

LOL I know and at this price range and made in Japan you can see why I'm concerned!
