I bought these hot air fryer due to the mostly good reviews. I was tired of my oven (with convection) for 2 rolls, or other little things heat up. The hot air fryer met my expectations. There is a small convection oven, no more, no less, but it is not deep fat fryer with oil! Meanwhile, you have to be aware of. French fries are a little better than in the oven, but not perfect. The volume is bearable, the cleaning is easy. All in all a device that can be used in many ways. You have everything but once taste until you have the correct temperature and duration found
