I like the protein mixture in this blender cups. I didn’t notice it leaked, the steel ball can
Stir well. Purple is completely purple.
The best quality improvement of this gfuel shakers cups is the serrated rubber handle in the middle. There is no sweat on my hands. Screwing on the top cover is the second best quality improvement, much better than pressing down so that the top cover is always completely closed. I highly recommend this shake bottle mixer, I have already bought the other two.
Easy to mix my protein shake. Leakproof, fits my size. I will buy another voltrx blender bottles.
