This is electric shaker machine is a nice product. The ones I have used in the past look similar but without the blender balls on the bottom. We used 8 ounces of milk and mixed a scoop of the mixture. The protein shaker mixer motor is strong enough to mix completely and the mixture does not sink to the bottom. I’m happy to say that there weren’t any nasty powders or any unmixed chunks left behind.
This electric shaker bottle is perfect for my protein shakes and works better than I thought it would! It works just as well as my blender with metal. The electric protein blender is easy to clean and is a great size. The quality is great, I love the purple color, and the graduated lines on the cup are clearly visible. I love this electric mixer cup!
