Mixed Bag
My second review of this product. I've had this oven for 2 weeks. It performs very well but there are some serious issues. Firstly, when I am using it for more than 15-20 minutes one of the fans stars to make a sound which could only be described as a bad bearing. Other have mentioned this but KitchenAid seems to brush it aside as "normal" Secondly: This oven is advertised as having a "Non-Stick" interior. I's only used it twice to cook something that produced any grease and thought I wiped it down the interior thoroughly. I guess I didn't. On the top of the oven, above the heating elements is baked on residue that simply will not come off. Others have mentioned THIS issue as well. Nothing KitchenAid suggests will remove it. This is the top of my oven after 2 weeks of light usage:
    Very beautiful. Easy to use. Fitts perfectly in just about any space. Quite. Had it about 1 month...

        Saved My Thanksgiving
        [This review was collected as part of a promotion.] I originally bought this countertop oven to supplement my main oven for small things here and there. I waited after I got a sense of how it works to write this review, and I've got to say that it has exceeded my expectations! Before I started using the oven I placed an oven thermometer inside and waited a few minutes to see if the temperatures were accurate and they are, for that I am very pleased. This oven is very spacious, I can fit a quarter sheet pan or a regular 13x9 inch pan well. The day right before thanksgiving my main oven stopped working and just when I was ready to give up I realized that I could do so much in this little oven. I made sourdough bread in a cast iron dutch oven, baked 2 small hams in a 13x9 pan, and made paella and osso bucco in an 11 inch X 3ish inch tall rondeau, it can even fit a 5 inch tall dutch oven if your lid isn't too tall. I haven't used it yet for cookies or roasting chicken and such, but as evenly as it heats, and as well insulated as it is I am sure that it will excel at these tasks. The interface is super easy to figure out, the space inside is great and this bakes so evenly. It also goes without saying that this countertop oven looks and feels premium. I love my Kitchenaid products because Kitchenaid stands behind their products! I couldn't be more pleased with my little oven. I'd love to one day get to have a gas range made by Kitchenaid, in the meantime this is just a wonderful investment.

            Faster than your average oven..
            [This review was collected as part of a promotion.] We got this oven a few days and have made pizza and homemade cheesy garlic bread in it so far. We are just getting started though. I think this oven would be perfect for a dorm room because it’s more compact yet faster than a regular oven. This convection type oven cooks faster than a common oven so you need to check on what you’re cooking because it might burn. Easy to clean tray on bottom of oven. It warms up quickly and has preprogrammed times for many cooking tasks. It has a timer to help prevent overcooking. We want to try making many dishes in this oven including meat and potatoes. I recommend this oven to all.

              Heats evenly, many thoughtful details
              [This review was collected as part of a promotion.] I am a huge fan of toaster ovens. They heat up quicker than regular ovens and are much easier to clean. This Kitchenaid Oven combines a lot of the best features of both types of ovens. You can use it for all the usual toaster oven features such as toasting bagels or bread and it's big enough to cook a whole roast chicken. This oven is a bit taller than my usual ovens as most of the controls are located at the bottom of the oven, but it's also a little narrower. The unit is sleek and the tempered black glass looks great on the counter. It has one of the best looking interiors when illuminated - your food looks like a work of art! Unlike other toaster ovens where the drip / crumb tray is located at the bottom of the oven, this one is located inside the oven. At first I didn't like the placement because I thought it left a lot of wasted space within the oven, but as I used it more I grew to prefer it as it made cleanup much easier to have your drip tray ABOVE the heating elements where you wouldn't have food dripping and burning on the heating elements. The unit heated up quick and my toast came out evenly browned. Most ovens are silent. This oven beeps as you press the different settings, I didn't prefer it, though others may like the audio feedback. A nice touch on this oven is the heating probe. I've used external temperature thermometers before and they were always messy while in use. Much nicer to have it plug in directly to the side of your oven and not have wires protruding out of the oven. It also comes with all the main cooking pans you need for the oven, including a a chrome plated steel broiling rack, an enameled multi-purpose pan, and a chrome plated steel oven rack. The instructions warn not to have anything within 4 inches of the oven and a lot of heat does radiate out of the unit so be careful with that, but it's no more than other toaster ovens. It's a nice touch that the top of the oven is designed to serve as a cooling rack space. Overall, so long as this oven fits under your counter it's a great versatile unit at a very reasonable price point.

                [This review was collected as part of a promotion.] This oven is awesome! The preheat time is extremely quick compared to a regular sized oven. Not only that, it has cut my time in half when baking. I also love that there is presets from the oven temp and time of cookies, frozen pizza, broil, and roast setting. I would definitely recommend this for camping, or used as an additional oven during the holidays. I wish it was a little bit bigger, but in my opinion, that isn't a deal breaker.

                  Really good quality convection oven
                  [This review was collected as part of a promotion.] This is not my parent's convection oven. It is so much better! This convection oven has quite a large capacity and preheat quickly. I baked a peach crisp in the oven and it was done in about 25 minutes compared to 50 minutes in a standard oven. The unit cools down very quickly too, so you wont have a hot kitchen for as long as you would when using the oven. The oven comes with a roasting pan for cooking meat which is nice. Kitchenaid hit the bullseye here with this convection oven!
