I have tried many electric shaker bottles, but they all seem to have shortcomings. I’m not sure about the flexible devices used to provide some extra content mixing, but they do work. According to what I mix, I don’t use it all the time, but when using soy milk and soy flour to make protein drinks, there will be obvious differences. Make the electric shaker cup beautiful and smooth. You can also mix up Bloody Mary!
This protein mixer jacket fits perfectly and does not leak at all. It takes a bit of charm to open the lid and clamp, but once it is done, it won’t leak. I usually only hold it with my thumb, which is also very useful.

I have two different sizes, the tops are interchangeable, which is cool. I got rid of almost all the other models I own, so there is no mismatch between the top and the bottle-this is a PITA. The size of the opening is also very good, very good, because my hands are so big, everything can be washed by hand.
There is only one negative that may be related to my hand washing. Over time, the swivel joint of the shaker bottle hat arm began to look a little fashionable. So occasionally I would soak them in the sink with a dilute solution of bleach to eliminate the peculiar smell inside. Other than that, these are great and I highly recommend it to anyone looking for a quality electric protein shaker.
