We use protein powder instead of Glucerna or Boost. “Pink” is cheaper than the two mentioned above. Try to use only glasses and spoons, but it’s a bit messy. Decided to buy these custom protein shakers, buy these, because you have two. The package arrived on time and was well done. These bottles seem to be made of high-quality materials. The lid is drip-proof when shaken. The “snap” cap is difficult to close and open on one of them, but it is not a transaction breaker. The “measuring tool” on the side of protein shaker bottles is convenient for us to view and use. This ball mixes well. All in all, this is a good product. But we are “new”, so please accept our suggestions accordingly.

  I like these smaller electric water bottles. They are perfect for protein shakes after exercise. I always have bigger obstacles, and they are usually too big for my purposes. You don’t need an oversized electric cherry bottle to get protein or something before exercise. These fit anywhere. These protein shakes are easy to clean and can be used for a long time. I highly recommend these! I have recommended them to all my gym partners because they have larger versions and are very interested in smaller versions.
