I think I could live with all the other components being metric, if they just had a way to work with standard U.S./Imperial containers as well.
As far as I know mason jars (of that size) are the same everywhere so it should work with whatever containers decided to use that standard
Oh, and they need a 120VAC design for the motor and all the electronics inside.
After reading the BOM it looks like the only electrical components are the limit switch, rotary switch, motor, and the support components soldered to the motor, so a 120VAC design would only need to replace those with equivalent 120VAC components.
Or, a design that can handle both 120VAC and 240VAC, as well as both 50hz and 60hz.
AFAIK that would either be a 120VAC model with a PCB to compensate in 240VAC areas or a DC motor with PCB

Possibly interestingly, some places in the world aren't either 120v nor 240v. Japan for example is 100v.
