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!
