I ordered this hob and it was delivered very quickly. I have installed it right, what went well without any problems. Then came the rude awakening: The plates were completely decentered, ie after switching on 1.5 cm next to the mark, the plate was about when heated hot. I then started a second attempt, however, tested the device this time before installation. Same result. I talked with the manufacturing company. They were very nice. I send you the part and then I get it back with a letter that the hob is now repaired again come back to me. But it was not so. Already decentered again. I gave up and decided to go for another manufacturer.
