Anyone have any experience with Canidae Grain Free?

[Chris & China (GA)]

While out and about today, I found a new food I'd never seen before and although I know the Sweet potato is a starch and can cause some issues, it sure seems to be a big thing now to add it into pet foods.

Just curious if anyone has ever tried it or opinions in general about this food

Canidae chicken/turkey/lamb

Canidae salmon/mackerel
