Voltrx electric bottles perform very well. Using water to make them into a protein shake doesn’t leave any lumps or powder, just a very smooth textured shake.
It’s easy to clean, a great size, and overall great. The BPA-free , ultra-high performance seal is leak-proof so we can use it without worry and it won’t get wet in our backpacks when we carry it. I usually take my protein bottle with me to the gym after a workout and enjoy a protein shake.
