Plenny Shake do not taste anything. My biggest worry before ordering was that I wouldn't like the tast of any of the 4 bags but they do not have any taste, so that's not a problem. If I'm generous they taste like grainy water with a hint of what the bag says, if you use your imagination. Not even chocolate taste anything, wich usually is the best taste in these kind of shakes. I drink one for breakfast and another for dinner and it works as expected. One pro for Plenny Shake is that the feeling of satiety is better than other brands I've tried before. I'm not disappointed but I won't probably order more, just for the lack of taste.
