I like this mixing bottle! I put water in, shook it, and gave it a good test to see if there is any water leakage, and it passed the test. My suggestion is that if you use the bottle at work or at home, please do not close the bean sprout cap completely. This prevents wear and tear that is most likely to leak. Just close them enough to allow the closures to touch each other. Practice this and your electric bottle opener will last longer.
I checked the extra protein shaker blender at the bottom. I can drink my breakfast milkshake in the morning, put it in one container before I exercise, and then exercise in another container instead of putting them in those big containers with me. I don’t have any leakage problems. I like the safety when the top is closed.
Ok, this protein shaker bottle looks like this, a very good best protein shaker bottle. I have no complaints. I have a problem, the lid is leaking, but the protein shaker price has a leak-proof guarantee. If you show proof of purchase and leakage on their website, they will provide you with replacement parts for free. Stackable powder/pill containers make my life between the gym and the office easier. I highly recommend this bottle
