It's ok. Not good, just ok. My experience: my old oven was very good. It cooked potato slices with chicken at 200° C really well in about 45 minutes, and it cooked a medium pizza at 250° C in 15 minutes. Then it broke and I needed a cheap replacement.
I chose this because it had good reviews and is cheap, but I'm already starting to regret my purchase.
Build quality: it's a box of thin metal with 2 heating elements on the bottom and 2 on the top. They are straight and set next to each other in parallel. The oven feels pretty lightweight and cheap as you handle it.
Performance: the temperature knob goes between 90° and 230° C, but it doesn't seem to reach its max temperature. The pizza took me about 30 minutes for the dough to cook enough, and it ended up crusty around the edges and soft in the center. It was cooked indeed, but unevenly. The chicken and potatoes "slices, not chunks" took over 1 hour at 230° C and they were still unevenly cooked. Some potato slices were soft as expected while the others were still raw and crunchy. The chicken was barely done.
What I assume is that this oven has a very poor isolation "if it even does". That causes a lot of heat to escape into the surrounding atmosphere rather than staying trapped inside the oven, which is the possible reason behind the uneven cooking and the atrocious cooking times required. I'm using the oven in June "weather is pretty warm" and I expect it to perform even worse in winter when it's colder outside.
My second thought is that the heating elements that are placed as straight parallel lines instead of a zig zag are causing the heat around them to be higher than the heat in the gap between them, which is causing the uneven cooking.
Final thought - Do I recommend it? No, I don't. If you're on a very tight budget, then by all means go for it. It functions, but keep your expectations low.
