I bought the chocolate and coffee powders. The coffee powder does not taste like coffee. The taste is mainly creamer. If the flavor tasted more like coffee and if it dissolved a bit better, it would have been a much better shake in my opinion. However, the chocolate tastes better like chocolate, but It can still be improved. More chocolate flavor! When you add extra chocolate powder you get what you expect. So I would say make the shake more like that. Also here the dissolution can be improved. But the shake is very easy to prepare and if you wait 15 minutes after mixing, it's like a milkshake, which I liked.
