The voltrx protein shaker is good value for money. I will have these for many years.

　　This electric shaker bottle is great. I can put the powder first, then the liquid, there is no powder agglomeration at the bottom. I hate all other electric blender bottles. Easy to carry! It can measure 22 ounces of liquid. Easy travel!

　　Great. Will not leak when shaking. Most of the Bill protein shaker electric I used before the leak. This is leakproof. I am so glad I found this milkshake bottle

　　These are great for making smoothies quickly. I found that some smoothies recommend using a shaker instead of the protein shaker bottle. In line with expectations!

　　This electric shaker is very strong, I like it. I have used other electric shakers before, but if you squeeze them hard, the plastic may bend or press in. The bottle, lid and metal ball are very strong, even though they have been washed in the dishwasher more than ten times so far. feeling not bad. Matte black looks great.
