“This is my second plenny shaker, the first of which I received from my friend when he started ordering plenny shakes. The first one cracked from the lid and I'm feeling the second one starting to leak a bit as well. I might be a bit too rough tightening it, but they haven't felt too robust to me. Ok for a free product, but I would be disappointed in buying these.”
I understand, the Active Shake does require a bit more space due to the additional protein. Have you tried using the large shaker? It's designed to accommodate those larger servings.
“It's a bit smaller than you might expect, but it's enough to fit two scoops of plenny shake. It's got a grating at the lid so that the powder can be mixed. It works a lot better than those balls you get in protein shakers”
