It is important to note that only the Mixing Bowl sold either from Thermomix USA or Canada is compatible with the US version of the Thermomix®. An easy check is to look for the voltage indication on the bottom of the mixing bowl. US mixing bowls are engraved with 110, non-US bowls are engraved with 220/230.
