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 Christy Grizzle

Slider tab was difficult to close (pre-filled inlet but that's true, although I don't care because it's tight). My concern is that the silicone seal will fill with water without the water being removed and drying causing mold. had to remove the seal to fix the problem but now it doesn't seal properly. When whole the glass is amazing and would be nice to keep using, but without the seal (but no mould) it can't be shaken to mix cocktails. A NOTICE. The star count has been increased because the new stub has been shipped and is working as expected.
