I'm having trouble with gaining weight and thought Jimmy Joy would be a great addition to my meal prep and routine. The first couple of tries I had to tweak the measurements for thickness and enrichment, but once you get a hang of that, it has a nice flavour and makes eating and traveling very easy. Unfortunately, I noticed my stomach got upset after each drink, and after a month of trying I wanted to send back the other try packages. No use in having it and waste isn't my thing. Luckily, Jimmy Joy understood why I had to give up their products and we're very helpful in sending the packages back. I didn't mention money guarantee back (because I'm well over the "due date), but that's what they offered anyways which is very kind of them. Tldr; great product, great service, great philosophy, unfortunately my bowl disagreed...
