Review on 🏋️ 20-Ounce BPA-Free Shaker Bottle with Action-Rod Mixer, Motivational Quotes, Dishwasher-Safe Protein Shaker Cup – Mind Over Matter - Maroon/Rose - 20oz by Elvis Kimbro

I was pleased with the performance of these shakers. I was afraid they wouldn't be up to the task. However, they serve their purpose. They mix the powder well without leaving any marks on the inside walls of the vial. No lumps of powder remain in the cocktail itself either. + for performance. Durable and stylish, they won't leak out of the caps when shaken (as long as you confirm the caps are fully closed). The only issue I have is that the construction makes them a bit difficult to clean. Because the metal resembles a spring-loaded, positive-locking design rather than a loose shaker ball, cleaning the lid and nozzles is a bit more difficult. However, it is doable and I believe this design works in favor of performance.
