Protein Shake Mixer

I was wandering if anyone had any tips on mixing a smooth protien shake. My blender seems to make it to thick, and my Blender Ball Shaker leaves it lumpy.

Maybe you could use more liquid or less powder? IDK?

I use a little hand held mixer....10 bucks at Walmart...works great for my shakes. =0)

Ditto on the stick blender.  They work wonders.  I have even used it to blend food as well.   Adding a bit more milk helps as well.
