Ovention Matchbox M1718 Precision Impingement ovens save you time, energy, and money — not only in cook time and electricity, but also in labor. The Matchbox uses a proprietary technology called Auto Load and Unload. This moves the cooking surface into the cavity at the touch of a button, beginning the cook cycle. Once the cook cycle has completed, the cook surface will automatically exit the cavity. This saves four steps compared to a manual load oven, saving time and making it simpler to use.
