Two weeks after I got this best electric shaker bottle, a part of the motor attached to the bottom of the voltrx premium electric protein shaker bottle broke. I think I unscrewed the motor too fast.
Anyway, I contacted customer service and they got back to me quickly. Their customer service was excellent and replacing my product was a breeze.
The portable electric protein shaker bottle itself is sturdy and feels great in my hand. The motor is large, but very quiet. There were no large chunks in my protein shake. This promixx miixr electric shaker bottle is also very easy to clean!
I use creatine and it takes a long time to dissolve, so having this little automatic shaker bottle is a great idea. miixr pro electric shaker bottle itself has markings that tell you how much liquid is in it, plus The voltrx electric shaker bottle has amazingly strong power. The battery lasts up to ten or fifteen times until it runs out of power. So if you want to use the electric blender shaker bottle, you must remember to charge it more often. Overall a great product!
