I have overall positive views of Jimmy Joy (via plenny shake) because of ease and price point. The flavor is ~just~ good enough to where I'm not miserable drinking, and the cost per meal makes it even more worth it to me. Flavor-wise, it takes like fresh flavored water-y mud. That probably doesn't seem like a positive, but I don't mind it. I usually add more water per serving to make it seem less gritty/thick. I use the plenny shake most days; it has helped me not go out for fast food and I run a lot, so I think the protein and carb amounts are useful on my longer run days (and it helps keep my stomach from getting upset).
