A protein drink is my favorite way to fill myself up when I'm short on time. Before protein drinks became a staple in my life, I used to try to blend protein powder into my coffee with a spoon. The blend was a filling drink but had a ton of clumps. Then I switched to a blender, but cleaning it felt like it wasn't worth the trouble.
That's when I did some internet research and found that there are devices specifically meant for blending protein. After years of going through various protein shaker bottles, I've found myself consistently reaching for these four.
