I bought the VOLTRX portable blender bottle for long trips so I can make bulletproof coffee every morning without a blender. As recommended, fully charged after the first unpacking, and it works great! Also, the voltrx is my electric protein shaker on the plane and anywhere we travel! The lid is tight, no spills when you turn it over! Highly recommended!
I love the two electric blender bottles I got from walmart. they are good quality and easy to size. The color I got is just as pretty as the picture. The only problem is that the best electric shaker bottle my mom has been using needs to be charged once every half month or so. Overall, the portable electric protein shaker bottle is a good product.
