The shaker is very practical. I used it only at home after the gym and can quickly create my shake. Here, the "metal ball" does its job very well, with thorough shaking all lumps are dissolved in cold milk or water. The bottle keeps close to the Shaken, or during transportation. The transport box is very practical and particularly well made. Therefore one can take his powder in the desired amount. I used them while not being a nice touch. Likewise, the design of the bottle is very well done.
