Very long, we were looking for a stove and finally decided on the Siemens induction. The cooker we have now for over a month in use and are absolutely delighted. With the retractable knobs you can control the temperature in 9 steps, whether fast cook or keep warm long everything goes perfectly. The oven is also very good in the handle. We have a baking tray of a soft close. There are of course other variants Siemens but let everyone decide for themselves. A high temperature can be achieved quickly because there is a quick heating function, but you have a choice. The different back programs leave nothing to be desired. The description is understandable and the stove can be operated very well. My wife wanted something modern but nothing robbed by complicated technology unnecessary time, and that's Siemens with this stove quite successful. The self-cleaning, we have not yet carried out, more on that later ....... We would buy the cooker at any time.
