The shakes are pretty good, they don't have a chalky thick feel, but not a too watery taste either. That said, I prefer the coffee and vanilla as compared to the chocolate and cacao green because they taste a bit like chocolate water to me, but that's just me. While I know what flavors I will now buy rather than the sample pack, I wish they didn't include a second green incase it's not for you. They all taste better cold.
I wish they had more vitamins/minerals in their shakes as I replace a meal with them, but I am really glad that they include fiber while other protein shakes don't.
