The round bottom of the voltrx protein bottle makes it easier to clean and mix the powder completely.

　　I have been an athlete for many years. For many 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 protein shaker electric. This is an absolute game changer. You can drink the perfect protein drink quickly and easily every time. Also easy to clean

　　protein shaker. When using the bottle electric, make sure that the nozzle is stuck firmly... My first protein shake finally spilled on the kitchen wall. Oh dear.

　　This blender bottle electric is the right size. Very strong. The round bottom is very easy to clean, and 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 save a dollar or so to get an old version of this cup, but I'm glad that it didn't. The round bottom is a great idea!

　　Shaker bottle electric is perfect for mixing protein and creatine! It will not clump like when you stir in a glass with a spoon. Be sure to clean it immediately after each use of shaker electric, otherwise it will produce peculiar smell!
