The smooth surface provides the slick look we were going for. The power boil is fabulous!! And it does boil water fast! The feature I use the most is the air fry - it works wonderfully and crisps veggies while keeping the inside soft. Delicious! I would have rated this a 5 but the broil option does not perform as well as I would have liked it to. Other than that, its a great buy and I would recommend it to anyone (and actually have already).
