It's fantastic and doesn't leak! Recommended
This shaker is brilliant. Solid construction. I've used it with both protien and creatine. Mixes perfectly and doesn't leak no matter how hard or which way you shake it. I definitely recommend the USN tornado protien shaker.
Save your money
Would give it 0 stars if I could. Constantly leaks when shaking and if it’s laid down. Spills all the time, not worth it at all.
