Review on 🥤 ShakeSphere Tumbler: Protein Shaker Bottle, 24oz ● Innovative Capsule Shape Mixing ● Hassle-Free Cleanup ● No Blending Ball or Whisk Required ● BPA Free ● Effortlessly Mix & Drink Shakes, Smoothies, and More (Sleek Matte Black) by Rebecca Carey

I bought this and protein blender cup. This product has problems and I am returning it. The BlenderBottle mugs are amazing for half the price. Problems -1.) The price is too high for what you get twice less than the design. 2.) The sliding lid is poorly constructed. Makes proper cleaning under the sliding part difficult. It slips into the lip when drinking, which is annoying. Bad complex design for no reason. 3.) Dishwasher permanently leaves white stains on matt black surfaces. Looks terrible after 2 washes. White spots stay forever. Other mixing cups have no problem. 4.) Bad, overly complex design that creates problems instead of solving them, costs twice as much as the competition.
