Positive: Great taste, even better than Joylent. Perfect solubility, no clumping. Very fast delivery. I love the taste tester package. Lots of variety in taste and kcal / bag respectively protein / meal. High protein content with normal and even higher with Active variant. Negative: Shaker bottle (although free) absolutely sucks, doesn't even close properly, strong plastic smell. More expensive than Joylent, Nutrilent and Nano, but still cheaper than Jake, Veetal, Huel and Soylent (Actibest).
