Query: Slow Cooker

I was disappointed by this cooker. It takes 23 minutes to cook a pizza to my liking in the oven. It takes this cooker 30 minutes to do the same. $50 is a lot to pay for something that doesn't work as well as an oven. Steer clear of this waste of money! It does work, but you need to wait longer for your pizza.
