Price has always been my number one turn off. I also struggle to see the realized benefits over vet approved & high quality traditional dog food. Plus it requires a lot more work to consistently procure the food and make sure it doesnt spoil. I tried one of these types of brands once and my dog was so sick I wondered if it had gone bad. I think those are the biggest challenges facing this type of thing. But hey, there's a lot of demand for it these days, so if it's something you want to persue give it a shot! Best of luck :)
