I have had them since 2017. When I bought them from a big chain, I got them along with 4 kitchen utensils for a total of 650 euros. When we installed them, it turned out they were defective, I immediately contacted the company and they brought me new ones and installed them themselves.
Now, in terms of functionality, I am very satisfied. It has a timer, I have worked with 3 eyes together and with the boost I have three-phase power at home and the hobs have their own safety. They heat up and cool down very quickly, they are very easy to clean, of course they have some scratches but I have had them for 7 years with almost daily use.
In these years, they have shown an error twice and the manual simply said to turn off the safety and then turn it back on after 1 minute, and fortunately there was no issue.
Overall, I wouldn't change my induction hobs for anything and of course they are much more economical in terms of electricity compared to ceramic ones. Induction with closed eyes.

Inductive guarantee. Very satisfied with their performance. I have been using them almost daily for 9 months. Extremely fast and easy to clean. The only negative is that the buttons should have a separate button that automatically closes each eye. Because now if you work with multiple eyes at the same time and want to close one, you have to constantly lower it, for example from 9 to 0, by pressing it with your finger. Also, the protective cover around it is not of such good quality. It made marks immediately.

In terms of functionality, they are very good. The water boils very quickly. It has a child lock and a timer. The temperature is adjustable with great accuracy.

BUT, they are very sensitive. Within a month, the stainless steel frame is filled with scratches. We have never scrubbed it with a sponge, only wiped it with a cloth and water.

The same goes for the rest of the piece. Very sensitive. I don't know how the appearance will be over time.

Big potato. The service from the dealership is disgraceful and unacceptable. The burners give errors and turn off by themselves. You can't cook anything and leave the food on low heat. I can't have two burners open and functioning at the same time, they both give errors and then I have to wait for them to cool down to open again. The dealership's response is nothing, maybe it's the cookware's fault. The cookware is brand new, specifically for induction burners and purchased together with the burners from the same store. It is the cookware that the dealership itself recommends for use with this specific appliance. In conclusion, do not buy Bosch burners or ovens. Such a waste of money. A big disappointment.

I chose it because it is very powerful. I was looking for one with high wattage so that if I wanted to use all the burners occasionally, with the boost set to maximum, it would not automatically reduce the power like most models with lower wattage do. However, I did not take into account the capacity of my house. A medium-sized house cannot handle a water heater, oven, and all four burners on at the same time because it exceeds the 35 amps provided by the power company. So, it is a very powerful machine, but in order to avoid limitations, you need three-phase power, otherwise you have to adjust. Not that anyone would turn on all four burners to cook, but let's say up to three burners with the boost activated, the power drops. I have had it for a week and I don't have an opinion on durability yet. One negative thing I have noticed so far is that the touch buttons require a lot of pressure to respond.

Edit: After two years, I am still completely satisfied. Only the frame has scratched a bit, but I don't really mind. I intentionally chose a model with a frame to protect the edges, as they are made of glass and I was afraid they might break due to power consumption. They burn less than the ceramic ones I had before, and because I read in other brands' reviews that they don't work with small coffee pots because they are too small and don't magnetize, I have even used a small Greek coffee pot on this one.

2 years that we have them they are perfect... very fast, no comparison to the ceramic ones we had before. It turns off each one separately with easy time programming, you don't worry about forgetting and burning the food.
