The GREATIC difference

The electronics stay in a replaceable magnetic base.

The powered base attaches without tools. Keep a second base ready to rotate, or replace a confirmed base-side battery or electronics fault without discarding the stainless-steel mug body.

  • Tool-free magnetic attachment
  • Second-base rotation for longer routines
  • $45.00 accessory price
