Works Great

This product does exactly what it is supposed to do. Mixes very well!
I do not know what else I can say about a mixer bottle that mixes things the way that is it supposed to do

My favorite shaker cup

Finally a shaker cup that will last! Most shaker cups come with a loose metal ball that you shake and bounces around in your cup to break down the protein powder and remove the clumps. After a period of time, the hitting of the ball creates damage and cracks the bottom of the cup. With the new Supplement King shaker cup, there is a stick that goes through the ball, making it go up and down the stick without hitting the cup.
