More ups than downs

- Not all my pots / pans work:
Was I clear beforehand, so no shortage. Everything a magnetic ground has (previously already tested) works as expected.

- Fan noise:
Not really. Yes can be heard, as well as penetrable as some people here do not describe again. My hood is loud, and even the sizzling in the pan covered up the fan.

- Beeping:
If you press a switch as well feedback. Otherwise, there are none.

- Power:
Better than my old electric stove and cooking such as gas. On / off, perfect.

- Lifespan:
Remains to be seen. In my view, you should really keep an eye on the prize here. The quality is really good and for the price, there is hardly anything comparable or even better on the market (alternatives bring it on). I am even inclined to pinch me a second to purchase and the electric stove. For the price I would have no problem if a time should be something defective earlier.
