Very difficult to clean. It is 7 years old and the black writing around the knobs is disappearing. The wok burner is too powerful, you have to be careful when you turn it on. I have an old Fisher & Paykel in my holiday house and it is a dream to wipe down. Not impressed with their oven either and it only came with one rack and a tray. Cost approx. $100 for another rack. The cavity is small and I often burn myself getting food out of it. As a serviceman told me many years ago "buy top of the range on a cheaper brand than bottom of the range on an expensive brand". Unfortunately the Miele cooktop and oven came with the house when we bought it.

The big burner is not designed well because the igniter is far away from the centre. Every time I ignite it I can smell a strong smell of gas and sometimes very hard to ignite successfully(Should try many times). However, service staff claimed that is not product failure or setting error, means I pay $200 but slove nothing.
It also not powerful enough.Although the official website indicated that the big burner is 4kw, it performs like 3.5W.
The black stain mentioned by other people also happened in my one

After a few weeks dark stains appeared on the burners.
I went to Miele and was told to buy their special cleaner gel. It didn't work.
Had some trouble with the burners too.
Overall, very upset with this purchase. Not the quality expected from any decent manufacturer, let alone Miele.

I've had a Miele KM 2012 G for 4 years and it's never missed a beat. I can't understand how people have burnt the knobs. I've never ben anywhere near doing that. The only thing I would say is that the wok burner would be better if it had some way of turning off one of the two flame rings - even on the lowest setting it's quite hot.

2 plastic hob knobs have melted-ones on left closest to the hottest burner. Just normal use. A design flaw. But it sounds like Miele will make pay $32 for each replacement knob. Maybe more now. Is there a generic alternative?
Should be $2 tops!
Otherwise happy though a way to get scratches out would be handy.

One burner is hard to light and keep lit, and the wok burner seems to be losing pressure, I've checked it's clean and without obstruction so I can rule that out. The old gas stoves used to last for years - the new ones, like this Miele KM 2012 G, not so. On the upside, trivits are quality. Would I buy again - no.

it is a very good gas hob compare to others in market. The finishing is flawless,a nd works safe and sound. Only the wok burnner sometimes is can be too powerful, that it heats up the metal controls next to it, and makes them a bit to hot to be touched.
It uses high quality Sabaf burners. Flame level is well controlled. Looks neat, and feels tough. safe and sound
The wok burnner sometimes makes the two left controls too hot for hand to touch on.
