Summary: I bought this product because a friend had one and she was quite pleased with hers. I've had mine about two weeks and have used it several times. Will take time to figure times for cooking. Guidelines are very helpful, but you need to watch what your a cooking the first few times to see how long it really takes to cook. Great for cooking with less fats.
Summary: First of all, if you are looking for a air-deepfryer, there is no such thing. I personally did not try to fry some potatoes with it, but it certainly does not "fry" meats. It's more like fan power oven; think it as a convection oven in a fancy housing. Don't get me wrong, this thing makes cooking VERY convinient, and meats get cooked very evenly, but it just isn't a "fryer." I wasn't planning to dip fry anyways, so it's no biggies for me.
Summary: This one is really convenient. The best use of it is to cook those pre-made "oven foods". It only takes 3 minutes to preheat, and the cooking time can be reduced by half compared to a conventional oven. So it makes cooking as simple as microwave, while keeps the better result of conventional oven. The only problem, which is actually a trade-off of oil-free frying, is the cooked food getting cold much faster.
Summary: I love this product!!! I don't like using my oven to heat up frozen (pre-prepared) food and the microwave zaps the flavor out of everything. This product is perfect for that. I have two pre-teens who get home from school before I get home and this product allows them to prepare wings and fries or fish sticks etc... without turning on the stove. That's one less thing I have to worry about. Love it. This product is pricey for the way that I use it.
