The voltrx protein shaker has a round bottom for easier cleaning and complete powder mixing.

　　I have been an athlete for many years. For years, I have been trying to "get in" the protein powder, but I always find it clumpy, foamy or rough. I am very happy that I bought this voltrx glass shaker bottle. This is an absolute game changer. You can drink the perfect protein drink quickly and easily every time. It is also easy to clean. When using the protein shaker, make sure that the nozzle is stuck firmly... My first protein shake was finally spilled on the kitchen wall. Oh dear.

　　This electric shaker bottle is the right size. Very strong. The round bottom of the electric blender bottle is very easy to clean. Any powder I add will not get stuck on the edge like a flat cup. The drink spout closed with a click and leaked. I wanted to make it cheaper, save about a dollar, and then buy the old version of this electric bottle shaker, but fortunately, I didn't have it. The round bottom is a great idea!
