What is the life expectancy of an induction hob?

Do these induction hobs work at 50 Hz, or is there some kind of
inverter involved, producing power at a higher frequency?
It's an inverter plus tuned tank coil generating a high
frequency magnetic field that induces eddy current and
hysteresis losses in the iron pot/pan, which then gets
hot. Note the need for iron, not aluminium.
The advantage is that the heat is concentrated only in
the iron pot/pan, the rest of the stove stays cool.
The disadvantages are the extra complexity of the inverter
and the associated extra cost and probable unreliability.
