No matter what you do, this will leak. I don’t have a defective product, it just is not leak proof and will leak all over my bag if even tilted at an angle. Leaks through threads when shaking, do not recommend Read more

We now have 3! The shaker top helps blend our hydration and vitamin powders great without clumps and uneven texture. Have not tried with thicker stuff like protein powder but expect it to be great too. Most amazing, it doesn't have an annoying to clean loud wire ball or spring as the agitator. Read more

El tamaño ideal, no tiene fugas, sirve para mezclar, no se raya. Read more

This is a great ingenuitive product. I always use the old cups that had the spring ball inside it, and it never fully mixed the protein powder in the water. Using this shaker bottle, I've never had clumps of protein at the bottom and it's always thoroughly mixed. The bottle is easy to take apart and clean in the dishwasher, but I suggest hand cleaning it with dish soap after every use. The bottle itself is really durable. I don't know how many times I've dropped this on a hard floor and it's never even had a scratch on it. I noticed it to be leak proof and I really feel that it's a great value for the money. Think of it this way, this bottle only costs about $1.50 more than the inefficient Shaker bottles with the metal spring ball. Well worth the price for the for a genius solution to the protein shake problem. Read more

At its price, nothing beats this shaker bottle. It’s of good quality, easy to open and use, no noisy rattle ball inside, shakes/mixes well, just the right size, no spill, good grip, very affordable, cool and simple design. It’s just perfect! Read more

Use this several times a week for my protein shakes. The part under the cap completely breaks up the protein powder for a liquid shake without clumps. I like that this product is dishwasher safe. Read more
