Very smooth shake that feels heavy with fats (might be a drawback for people who prefer having some texture in their shakes). Main attraction for me is the variety in flavours, which keep things from turning stale after a while (they even managed to make the vanilla flavour interesting, just as soon as I started thinking all vanilla shakes taste the same). The savoury flavours are rather weak and need a bit of work (the bacon one just kinda tastes like smoked salt), but they were an interesting experiment that I hope they stick with. Add the price and you got yourself a pretty good deal here. Might end up being my default shake just on the variety factor alone.
Biggest drawbacks are that it's not as filling as some alternatives, it can feel a bit sticky/runny/gel-like in your mouth, and the shaker bottle they ship for it has a nozzle that tends to spray when you open it after you shake your powder (no idea why there's so much pressure buildup).
