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 Daniel Bates

I had really high hopes for this product, especially as I don't have to deal with the "regular wire ball" on many bottled cocktails. The design is nice and the quality seems good too (can't speak to durability as I just bought it). As mentioned in the title, the performance is only mediocre. I've mixed my protein powder (using different liquid to powder ratios) and shaken the bottle over 50 times and still get unmixed/lumps of protein. In my opinion this bottle is not worth more than half the money I paid for.
