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 Karina Miller

I bought this to mix Slim Fast and Banana. Didn't work so well the first time with a new banana and adding almond milk before shaking. Since then I just add the banana first and shake it, then I add the almond milk and powder. The bananas are also a bit softer now, but I'm not sure if that matters or if it's best to shake the banana alone first. In any case, it's great. Looks great, washes just as easily as advertised and doesn't leak a bit. The slide latch is good there, so make sure you know which way to push it. I saw a review where they broke the top by pressing it wrong. I can imagine how that could happen if you, the gorilla, were to force it the wrong way, but even going in the right direction takes some force. Would buy again but don't think I'll need it.
