MEDIOCRE. It is not worth its price at all!
Reasons:
1. It has a short cable, it doesn't reach anywhere. It is about 1 meter or less. I had to cut it and add an extension to make it functional. So, the warranty expired from the first day.
2. The timer doesn't turn it off when it rings the bell!!!! You put the pizza in and leave or forget about it; you won't find it at home, not just burnt instead of pizza. Because at the temperature you set the thermostat, it considers it preheating and tries to keep it stable. So it will always be on. I thought about adding an on-off switch to make it more functional, but it won't change the danger if you leave it, even if the timer finishes and rings the bell. It has deficiencies and mistakes in its design. Serious ones in my opinion.
3. It can't fit anything other than pizza - you can't warm up a sandwich, for example. Let's say it's acceptable because it's specialized.
4. The plate gets very dirty easily, it sticks badly and you can't clean it afterwards, not even with the rough side of the kitchen sponge. I used the scraper that comes with it to scrape it off. Also, you have to bake many pizzas to find the right temperature that won't burn them and won't leave them with partially cooked dough.
5. Due to the above, the price shouldn't exceed 50 euros.

It is the first machine I have bought in years that annoyed me so much that I wanted to throw it away.
One positive thing? The plate can fit a large 32cm pizza, which is difficult to fit in many devices.

I do not recommend it.

I will come back after a week of quite a bit of use.
1) The timer is the most useless thing. You don't need to use it because it makes a noise. The thermostat determines whether it will work or not - CONSTANTLY! If it didn't exist, nothing would change.
2) It doesn't turn off at the zero of the thermostat! You have to unplug it. There is electricity flowing at zero! The resistance, if you touch it, is lukewarm, it has temperature.

3) No matter what you do, the plate will inevitably turn completely black soon.

The only good thing:
When it heats up, it bakes many pizzas continuously and quickly.
I baked 14 pizzas quickly. Maybe the only reason to buy it?
I do not recommend it, not even with explosives for household use. There is no reason. With a 4 euro oven, you can bake the same, if not better. Maybe it makes more sense with pizzas with fresh dough. I haven't tried it yet with fresh dough. Maybe the top part burns intensely before the bottom is properly cooked. It happens to me with the pre-made ones.

It needed an off switch along with the timer. An off switch in general, so it doesn't preheat even at zero. It needed a longer cable. It needed a smaller resistance in the top part, to burn less on top and have a bigger one at the bottom, and maybe it would be worth up to 100 euros. (Are you listening, manufacturer?) Now the price is a bit too much for such a poorly designed machine.

Good but far from being considered an excellent product, especially at the price of 125.9 euros it was purchased (which remained constant in 2021)! It requires experimentation in order to achieve the correct baking, and this is because despite its high price, it does not offer independent intensity adjustment in the upper and lower resistance, but rather a unified one for both... (the second switch is a timer)! In order not to be unfair to this particular oven, this is how similar ones are designed from what I have seen! So sometimes it almost burns on top without being cooked underneath, and vice versa (depending on the thickness of the pizza dough)! Over time, you learn to "play" with the baking time, the temperature you input the pizza, and also with the trick of opening the lid and letting the pizza heat up only from below! Finally, over time, the stone will become dirty (it will turn black in most parts) with stains that won't go away no matter what! Yes, the stone can be removed (a process is required for this), but I don't know if it's worth replacing! I hope I helped
