We have seen the product on TV and decided to try it. 1. We need the oven less 2. Energieverbruch opposite oven is lower 3. Preheat is not necessary 4. Cleaning is quick and simple 5. Almost no odor Unfortunately, not all is well. The build quality is OK but not very good that the plastic is not 100% accurately fitting and the handle has an edge, which is palpable. Looks like a cheap product from the Far East. However, since the function of the device is properly one can overlook this workmanship. We are so far satisfied with the device and can highly recommend it, but the price should not be significantly higher than 100 euros.
