I rarely write reviews- but I love this mixer. No tiny parts that grow mold, dishwasher safe for easy cleaning and no annoying clanging metal mixer ball. It blends the protein powder in with the liquid really well. It’s quickly become my go to shaker for protein drinks (I even ordered a second after quickly loving my first). The only thing that would make this better was if it was insulated and could keep the drink cold for a while.
Immediately when I got it I put it up to the rest of blending peanut butter, in milk no less, and a bit of vigorous shaking later it actually did it. I prefer monochrome glacier because I can see the color of the fluids to be sure everything it mixed properly. Plus I mainly exercise indoors so it's not a issue to have something slightly less sun resistant. A bit of baking soda and white vinegar deals with almost any lingering scent so it's pretty decent when it comes to cleaning. Happy to support a USA company!
