VELOMIX 2 Pack 28oz Protein Shaker Bottle, Blue/Transparent

It's a shaker. It does what a shaker should do. Personally, these are my favorite of all shakers. I love the colors and have purchased several as gifts....easy to clean, love the wire whisk inside and the wide opening.

Good solid water bottle -- tough to get wrong -- secure and no leak, good feel.

These are great! We got them to actually take our cold brew in while fishing on the weekends. It holds the perfect amount of liquid and the snap lid is very secure. It knocked over a few times while in the ocean and lid stayed closed. Very good and easy to clean! Will get more

I usually shake bottle clockwise with bottom down to make sure the powder dissolves into the water before shaking it up and down to prevent clumps from forming at top lid or spout. Works every time. And this bottle offered no leaks not even when spout not locked in and just my finger pressing on it.

I am sooooo happy with this purchase. It is a great deal for two of these mixer cups. These are always so expensive at health stores just for one cup. It fits perfect in my cars cup holder and they are super easy to clean! The lock feature is super helpful when I am in a rush and throw the shaker cup into my bag and dont have to worry about spills. I also love the bright colors that are also see though. overall great functionality. Also no weird plastic taste from the cups either!
