Can I make a good pizza in a home portable oven?
It depends on what you call "good". 

On the one end of the scale, you have people who don't go to pizzerias with an electric or gas commercial oven and insist on wooden fired ovens which get the pizza ready in 90 seconds. On the other end, there are people who will be happy with anything flat with a covering of tomato sauce hot enough to sear the roof of the mouth. Without knowing where you fall on the scale, I don't know if pizzas from this oven will reach your threshold of "good". 

But I will encourage you to make pizza in it. I have been using nothing but a toaster oven myself for the last 10 years, and it works well for me for all the usual purposes. It is better for pizza than the usual big home ovens, because its higher ratio of radiation vs convection heating is more similar to a fire oven than that of the usual electric home ovens. (Not everything is rosy though - this same quality makes it inferior for cakes and oven roasts). 

So, go ahead and make your pizza.
