I commonly use the electric protein shaker.

　　The VOLTRX products are not like a regular shaker bottle, they just have the dimensions on the side. The lid is easy to open, but I find that if you push the button, the electric mixer parts really well! So far the automatic shaker machine hasn’t leaked, which is a plus.

　　I bought this protein mixer machine mainly for the shakes I made this morning. The mixing blade was much easier for me than the shaker ball. All I had to do was pour my stuff in and just hit the switch. My miixr electric shaker bottle has no hard clumps in it and is much faster. I really like it.

　　This has become my best electric protein shaker for travel. i use it for water, shakes and smoothies. I like the blades to help break up the nutritional powder so it doesn’t clump when I’m making shakes at work. I also like that the electric shaker machine has no angles on the inside, just rounded edges, the lid screws on tightly and the drinking/pouring spout snaps on tight.
