Works well on so many levels I bought a basic Sun Oven over 25 years ago and am still using it. I got the new one for one of my friends. He loves the oven and tries to use it every weekend since he works long hours during the weekdays. We live in Arizona and by cooking outside, the heat stays outside. The interior of the house stays cooler and the A/C unit doesn’t have to work so hard. The new features which include the thermometer, siting capability, cooking racks, and pans are great.
