So far so good, entirely different means of cooking, having to unlearn 60 years of times and temps. Beware of cookbooks, lots are American with different recipes and ingredients than we use. The terminology is misleading too, it isn't a fryer as we know it, more like a mini turbo oven with the same heat in a much smaller area. It's not as noisy as I half expected, results so far are encouraging and while very few items are not much quicker, the amount of energy used is far less.
