Nah, sry. I just heard/read about them. One thing is using an inverter to control power instead of on/off timing. Other is using a bunch of sensors, that i remember as an idea many years ago.

Seems to have both (i just googled “fancy microwave” and it was the first result :)).

For my needs just a timer dial is enough.
