Review on 🍶 Hydra Cup [5 Pack] OG Shaker Bottles: 28-Ounce Protein Shaker Cups with Stand Out Colors & Logos - Max Value Blender Pack, Version Two by Brian Buck

The plastic mixing rack has no edge or edge to hold it in place in the cup. That means it will loosen up and turn sideways as soon as you start shaking. It's almost useless. Too bad mine came with the metal balls everyone else seems to get. They're just cheap plastic shakers. Leaking after a few uses. 2 lids are already cracked from trying to unscrew them to prevent leakage. Cheap imported products 99% chance that it does not contain BPA.
