I have only tried the apple pie and the chocholate-peanut flavours. The apple pie has a decent taste, but the other one is really bad. The powder does not disolve easily in the water, so even I have been shaking my Blender Bottle for five minutes there are still big lumps in the bottle. Storing it in the fridge did not help. Overall, I am quite dissatisfied with the experience.
Reply Queal:
Hello, we're sorry to hear that you didn't like the taste of Queal!
Taste is quite subjective of course, which is why we also have an unflavoured "In Qontrol" variant of Queal. Perhaps that is more suited for you?
With regard to the lumps; Do you put the water in first, then the Queal, as mentioned in the manual? This makes a big difference I have found.
