Kumtel mini ovens are of very high quality. I’ve been using it for many years. I didn’t have any problems. We cook excellent food. It is not harmful to health. When you put the food in, you can see it through the glass, so there is no problem of opening the lid and checking it again and again. Kumtel mini ovens are anti-rust and rust never occurs on their bodies. They already guarantee that. My favorite part is that I can easily clean oil, dirt, food residues. Easy to clean. I also use all kinds of detergents. There was no flaking or change in the color fading paint. I would recommend it, both visually very stylish and very high quality in terms of use. If I speak about the economic dimension, the products are very affordable and do not shake the budget. It also saves electricity while using it and don’t let to an extraexpenditure. It can be carried anywhere, thanks to its dimensions and light structure, it is compatible with everywhere. I use it heavily.
