Thoughts on Daiya Products?

Has anyone tried Daiya pizza or mac-n-cheese? Daiya is a company with only gluten free and dairy free versions of pizza and mac-n-cheese. I’m a little nervous though because of how inexpensive some of their products are. The pizza is 8$! Do you guys like them? Have you had any negative experiences? I’m on a flare and gluten causes irritation. I’ve not tried a lot of dairy yet but what I have tried hasn’t affected me much. I’m too scared though to try dairy cheese. What do y’all think?
