These are really excellent protein drinks. They are high in protein at 35g per can and low in calories, at 170 per can. I've only tried the chocolate but found it to be thick and creamy and very satisfying. The first can I tried I did NOT shake enough, and the bottom of the container had clumps of undissolved protein mix. That can also had a kind of tinny taste from the aluminum.
The next cans I shook very well, and the shakes were properly mixed. No tinny taste (nor aftertaste) was detected and it really did taste like a rich chocolate shake. Additionally, these are pretty low in cost to comparable ready to drink protein shakes.
