I added the 310 vanilla to my usual smoothie recipe and it tastes awful. I tried it with plain water as well to make sure it was the drink mix and it definitely is. The mix tastes artificial, has a terrible aftertastes and only mixes well if blended in a blender. Otherwise it is grainy and clumpy and unpleasant. I can't imagine how anyone would say this drink mix tastes great unless their preference is for strong artificial aftertastes and grainy textures rather than smooth. Definitely would not recommend.
