Great product
This cup is great. The bottom twists off and I can stash some granola in there to have with my protein shake after my WOD. Has a nice window in side so you can see/measure your liquid as you pour.  The top has slotted compartments where things like supplements/vitamins can fit nicely. My protein powder mixes great in it just by shaking it up with water.  I found the cups with the shaker balls sometimes clumped the protein powder.  It is larger than I was expecting but it still fit in my car cup holder which was the real test! I think this cup is great. !
