Economics and Philosophy

As you can see above this is the double deck pizza oven that cooks two 12" fresh pizzas in 90 seconds (or frozen pizzas in three minutes), allowing you to cook pizzeria-worthy pies 15 times faster than a traditional oven.
At first view it seems like silly business idea. But there are many advantages in this good.

Advantages:
• Much more productive
• Takes only 90 seconds to cook a pizza
• Not expensive( as you can see in the webpage it costs only $249.95)

• Don’t take a lot of place
• Cheap costs--- cheap product--- maybe demand increases(depends on PED)
Disadvantages:
• It may cause the market failure. By eating a lot of fast food people become obese . Just because it is cheap. But it also depend on PED
• It can broke and it would be hard to fix it
• It might be possibility, that very fast cooked pizza wouldn’t be tasty and nobody will buy it, so they may fail with this idea
• There are many substitutes of fast food

From my point of view, it is good stuff, but i wouldn't spend money for this.
