    Strong and sturdy

    Great bottle and lid, however, right after we received it, my son left it on the airplane.

    Great bottle!

    This is the one to buy. It has the real wire wisk, whereas virtually all other products have some plastic ball or claim theirs is designed to not need a ball or wisk - scam. And, this is one bottle that is gasket free on the lid and it will NOT leak. These are practically the only legit shakers available. I was very impressed with my first one so i bought 2 more and they are as quality as the first.

    Mystery item

    Although it's not as extravagant as my previous two mystery items, I can't say I'm disappointed with this 20 classic bottle. It's still worth more than I paid for it, and fills a niche in my collection. I take a joint supplement twice a day, and at night I prefer not to drink a smaller quantity of liquid.

    Using a smaller bottle frees up space in the dishwasher, and it will also be great for travel.

    Otherwise it's just the same excellent design as my other bottles, but smaller.

    Way to hit it out of the park again, Blender Bottle!

    Looks great, broke in two days.

    The new design looks great. The inside rounded bottom it’s a great idea in theory, yet in reality it leaves the cup bottom edge unsupported. Two days of use and a light fall from a 24” jump box it split from the bottom to the lid, rendering it useless.

    Common Questions

    What is the difference between the original Classic™ shaker and the All-New Classic™?

    The all-new Classic™ protein shaker bottle features upgraded features like a rounded base and a protected drinking spout.

    How many sizes does the Classic™ come in?

    Stock colors of the Classic shaker come in 24oz, 28oz, and 45oz. Officially licensed and Special Edition shakers may vary.

    What do I do if my shaker cup flip cap is hard to close?

    Hold your protein shaker in one hand and press firmly with the palm of your other hand on the flip cap. When you hear the popping or clicking sound you'll know your shaker cup is securely closed.

    The measurement markings on my shaker are less than the size of the cup. What gives?

    The total cup volume is measured to the brim of each protein cup (i.e. take the lid off and fill the cup until it reaches the top). The ounce and milliliter markings do not go up to the brim for aesthetic reasons.

    How tightly should I close my lid?

    Turn the lid a quarter turn past a snug fit.
