Review on BlenderBottle SportMixer 20-Ounce Shaker Bottle: Ideal for Protein Shakes and Pre Workout, Sleek Black Design by Paula Baker

I was mixing powdered protein shakes in a shaker cup but found they still had a gritty texture. The mixing ball in this shaker makes a big difference. I pour water up to the desired mark (marked with different water levels), then add a mixing ball (like a long paper clip rolled into a ball shape), then close the lid and shake vigorously for 20-30 seconds. . The result is much smoother than my old method. Everything is easy to disassemble and clean. I bought two of these to drink in the morning and evening in the fridge, chilled and ready to drink.
