Queal: pretty good so far. I tried Banana and Chocolate Hazelnut mainly for breakfast. Taste good and keeps me full to lunch, while with my normal quick breakfast I begin starving at 10.30. After one week of regular breakfast use, I did not notice any physical drawbacks. I also like the shaker and the packaging. Good job here, I'd recommend it. WUNDRBAR: not good. Can't eat the vanilla taste. I can handle the chocolate taste, but the experience is not satisfying. I do not even fill full after it. Won't recommend it.
