I was torn between two different blender water bottle companies, but decided to go with the VOLTRX Electric Shaker mainly because of its color. It comes in about 6 or 7 colors, but the price of each product varies depending on the color of the portable blender bottle.
Other than the color, I couldn’t see any difference in their selection; therefore, there was no reason to choose the more expensive combination, but I did buy a pink electric blender water bottle. they are both 24 ounces with a 20 ounce capacity.
