I didn't know that. I honestly bought it because it was cheap and if I was gonna mess something up on my first try I didn't wAnt to lose a lot of money. I've read on here that they can dry out easily. Yesterday I heated a piece up in the microwave for a sandwich and had to use two plates because the first one was soaked with juices after heating it up! Beginners luck I guess? Either that or I didn't cook it long enough but I haven't gotten sick yet so I guess it's good enough. Lol
