9. Does the Vortex-Genie 1 mix more vigorously than the Vortex-Genie 2 or Vortex-Genie 2T?

Yes. The Vortex-Genie 1 has a mixing orbit of 6mm, which allows for more vigorous mixing than the Vortex-Genie 2 or Vortex-Genie 2T. However, because of this larger mixing orbit, most accessories for the Vortex-Genie 2 and Vortex-Genie 2T should not be used on the Vortex-Genie 1.
