Suddenly, after 4+ years, it displayed 4 E and stopped working. I would say that the product has an expiration date around that time since the problem seems to be with the main board.

From the very first moment, marks from the pots remain that do not go away and it gets scratched very easily.

About three months of use. Very good burners. They heat up very quickly. They don't scratch easily as some mention in the comments. Overall, absolutely satisfied with my purchase.

Very powerful.. trust it. The only negative is that it scratches relatively easily. But we overlook that because it is perfect in all other aspects

We replaced an older Siemens of the same class that was 15 years old. If it lasts as long, it will be satisfactory!

Is it possible to make such a mark on the first use? It is not determined with a sponge and soap that I tried

I believe it is a good device. Like all stoves, it requires attention and quick cleaning. It is worth the money.

We purchased this specific stove on 9/12/2019 and it worked perfectly for the money. Today, after three years and while everything was working fine, it suddenly emitted a burning smell and stopped working because we are out of warranty. We contacted a technician who sent it to Athens for repair and informed us that the circuit board and some other component have burned out and cannot be repaired. In general, it is useless.

Excellent choice! Powerful cooking, easy cleaning! What else can one ask for? I highly recommend it!!!

I was very satisfied with this purchase. Fast cooking and easy cleaning. It really is worth its money!

Very good choice of stoves. Their quality is evident. They clean easily and are powerful in cooking. I recommend them.

I have no complaints. Easy cleaning, quick cooking, and easy to handle. Simply wonderful!!

I bought it about 12 months ago and I am writing for the first time because I am frustrated! The big eye that is protruding is not convenient at all because when you fry, the oil splatters reach the floor. The worst part is the locking button, it is so sensitive that it locks with the slightest touch but then it doesn't unlock at all... I have been forced to heat the food on the stove. After closing the kitchen's main switch and trying several times, then it unlocks. I do not recommend it at all.

After 6 months of use, it has not presented any problems to me. Cleaning it is easy, I use a wet sponge with dish soap and wipe it with a cotton towel, so it doesn't leave any lint.

I have been using the stove for about 8 months.
It is quite powerful (former owner of a 25-year-old Siemens turbo stove), and it is easy to clean. Another positive aspect is that it has "levels" of temperature adjustment, so with one click, you can set it to the desired temperature.
The negative aspect is that the lock it has only holds for about 2 minutes and then unlocks by itself, which is very annoying because when you boil something and water falls on the settings, it changes the temperature and/or turns off.

The eyes are good and the boost is very powerful. However, the user experience of the menu is tragic and terribly difficult to use, as every time you want to adjust the intensity on a specific eye, you have to select it first. If you're cooking on just one eye, it's fine, but it's difficult on 2 parallel ones, and simply unmanageable on 3+ parallel ones. The icons for which eye you're addressing are confusing, as they are aligned, and the intensity bar always ends up being chosen randomly to find the desired intensity. At first, I thought I would get used to it, but after 6 months, every time I use it, it still feels like the first time.

The stainless steel scratches very easily. Very good looks with very good handling (wet hands, etc.). After 3 months, the glass surface has scratches

The stoves appear strong and beautiful, however, on the stove with the booster, despite my careful attention, stains were created that do not go away at all.

The stoves are perfect, powerful, and easy to clean. If they also had a timer, there would be nothing better

It is the best you can get at this price, they are very easy to handle and really powerful.

They have enough power, they are noticeable but they wither with the heart of a lettuce

After ten days of purchase, the hobs are showing perfect performance. They are very powerful in the eye, and with the boost function, they bring water to a boil in a large pot in 12 minutes. Overall, they seem very good. Time will tell for any updates, and I will come back.

We have been using it for a month now and we work with it almost every day. It seems to work just fine. Be careful when drops of water or oil fall on it while it is working. Also, check your cookware because some of them stain it a lot. One of our pots ruined it, but with enough scrubbing using cif and the sponge for dishes on the rough side, everything came off and it became like new. (Not with a metallic sponge!) Now, instead of cif, I use vitro clean for stains. It's a small black bottle that is specifically designed for such stovetops and it cleans it much more easily. However, even with the sponge for dishes, even on the rough side, it doesn't scratch the stovetop at all.

Very powerful burners. My only complaint is that one of the 4 burners, even though it has boost technology at the highest temperature, does not heat well. Maybe I don't know how to use it or it has another usefulness that I haven't realized? Anyway, the rest heat up quickly.

Update: After a year of use, I consider it a good purchase, and finally, the burner also opens from the touch button in the middle of the stove.
