Outstanding protein and customer service
I like how the flavor is not overwhelming and the customer service was excellent. When I encountered an issue with shipping - it was quickly resolved.

Salted Caramel is IT.
Wow. Aroma, taste, mixing, even scoop friction (a metric I never thought I would care about until I switched from ON double rich chocolate blend that comes out of the provided scoop rather slowly) are all splendid. This ends up in my shakes with powdered PB and oats. People, let me tell you that it slaps. Just a delectable treat that I will never get tired of. Flavor is strong. Aroma is a delight. Not really all that salty. Digestion is another 5* with no grumblings or aches or regrets afterwards. Bought the two pounder to try it out but I'm going neck deep with the ten pounder next. My new daily driver.
