The BlenderBottle Classic Shaker Bottle does a pretty good job mixing protein shakes, from what we've gathered. It blends powders with liquid nicely, thanks to its wire whisk ball design that keeps clumps out of your drink.

However, there are a few things to keep in mind if you pay close attention to measurements. The bottle's total capacity is 28 ounces, but the measurement markings only go up to 20 ounces. This could cause a bit of confusion if you're trying to be exact, especially if you like clear measuring points.

Our research also shows that the measurement markings aren't the easiest to read, particularly on darker bottles. The beveled engravings can be hard to make out unless you're holding the bottle up to the light or right in front of your face. If that sounds like a hassle, some people actually add their own marks to make things easier.

This visibility issue seems to stand out more with the black ones. So, if precise measurements are important for your shake-making routine, you might want to pick a lighter-colored bottle, where the contrast makes reading the markings simpler.

All in all, despite some gripes about marking visibility, the BlenderBottle Classic Shaker Bottle does what it's supposed to do: mix your protein shakes smoothly and consistently. If reading the measurements easily is a dealbreaker, go for a lighter color, but you can count on it to mix well.
