It took me far too long to buy one of this:
I really loved my NuWave oven, but retired it after finding an open box special on what I consider the next generation of cookware. The Gourmia GCR1700 Air Fryer which makes stir fry, bakes, grills, steams, and everything in between. This takes up a little less space than the NuWave and you don't have to pick the heating element up and lift it off to open it. Instead, the very light weight hinged top flips back and you can just reach in and/or lift the cooking pot out.
So far, everything I have made in it turned out delicious. Today I baked in it for the first time.
This is a tomato tart made with a crust of oat and sprouted spelt flours. The topping from bottom up are garlic, cheddar cheese, diced tomatoes, and fresh basil from my AeroGarden planter. I used the grill setting on high to precook the crust and turned the temperature down after adding the toppings.
The controls on the GCR1700 are pretty intuitive. You just plug it in (I have an on/off switch at the plug so it can stay plugged in and I just turn it on when needed) and select one of four modes. The 2 on top (Grill and Steam) are for use without the stirring arm. Grill is for dry cooking (steaks, baking, etc.) and Steam is for moist foods. These modes have preset temperatures, but you can override them with the set button and press "+" for higher heat or "-" for lower.
The two buttons on the bottom (Stir Fry and Stew) are for foods that require stirring, and it is amazing how well the so-called robotic arm works. I have only had my Gourmia for a few days, but I have made both stir fry and a stew, and with excellent results. I also used the robotic arm to refry a batch of precooked pinto beans. Yums!
Although it is true that there are not a lot of recipes online for this device, common sense works well in deciding how long to leave the food cooking and how and when to adjust the temperature. You can pretty much see and smell when the food is ready and it cooks really fast. It also doesn't make a mess, no splatter, no spills, and the easy to lift cooking pot comes clean with nothing more than a spray of water. I seriously do not plan to ever use or have to clean a frying pan or stove (or oven) again.
In addition to this appliance I do heavily rely on my Insta-Pot multicooker and the Bella 8 in 1 grilling system (think Panini sandwiches, Belgian waffles, bacon, and grilled cheese sandwiches!)
