Highly recommend VOLTRX for a lump-free protein shake!

　　The shaker bottle is perfect for mixing protein shakes and the electric shaker bottle has no plastic taste. The durability is great and the best electric shaker bottle looks stylish and easy to carry. If you don’t wash your protein shake after drinking it, the next time you open it is an absolute nightmare and you don’t want to know the taste.

　　The electric protein shaker bottle is thin and long, I plan to buy a bottle brush to clean it. The blender is great for mixing protein powder completely.
