I’ve had one before and I don’t really get the hype. It’s an oven that heats up faster. I see the value in that but it doesn’t seem useful enough to take up counter space when I could just wait a few minutes for the oven.
It's cut my cooking time down by magnitudes, but even more so, my cleaning time. But I suppose it all does depend on the use cases. I, for one, plan on never having to wait for anything to preheat in my kitchen ever again!
