There are three reasons for my vote with only two stars:
1. Although it is sold as a "lightly sweetened", but is still way too sweet. If someone like me wants to reduce its consumption of sugar, an over-sweet punch on the taste buds helps such not really. In addition, the product leaves the typical consumer to unpleasant aftertaste of the artificial sweeteners used (which apply anyway as appetizing and fattening!).
If this is the "Lightly Sweetened" (slightly sweetened) product, then I do not know how horrible the normal sweet sweetened product.
2. In addition, the product contains taurine, which I did not realize before buying. Taurine seems some metabolic processes in the body to favorably influence, but are people who suffer from kidney failure, avoid taurine.
In addition, it should be a stimulant. I can confirm the latter effect, because since I now take a couple of days this product, I wake up at midnight, feel wide awake and can not fall asleep again. Can not be a placebo effect, because I, as already mentioned, until a few minutes did not know that taurine is included in the powder.
3. The powder comes in an oversized box that takes up a lot of unnecessary space in recycling garbage (or take is). The Giants can is barely 2/3 full. Why? Why such a big box, if not needed for the capacity? "Bigger is better"? Not really.
