Query: Inconsistent

My first purchase of Magma Plus was as the reviews read, for example the product was finely ground, tasted good and I felt good, exemplified by my energy level. The second purchase was disappointing as the product was of a different color, the product was not finely ground had a terrible taste and odor as well as the container was 1/2 full, I threw it out. In conclusion, there was no consistency between the two lots. I am reluctant to try another purchase as the quality control is disappointing.
