This is a fairly standard product. If you have used electric shaker bottles before, they will not overflow as long as you screw the lid on correctly. The mixing ball works well and is easy to clean. I recommend using an electric shaker instead of a sponge or cloth for washing, in case your hands are a bit too big for the electric shakers.
I absolutely love this electric blender bottle! The lid and spout are safe. I shook the contents vigorously, no water leaked. The circular stirrer inside is not lumpy. The only thing I don’t like is avoidable. The label is applied to the container with some kind of glue and will not fall off after washing. No, I don’t like the glue left on the product label.
