This is a good protein shaker bottle. I can’t mix powder. Before adding the powder, pour the water into the shaker and add ice cubes after mixing. I will give it five stars, but my Shaker Bottle does not have a “sweet spot”. This is just a blank. My fingers should be pressed on it so that it can be sealed. I bought a missing part for 39.95 dollars.
The customer service emailed me, saying that my vibrating screen is a new model, and the warranty card in the box has no missing parts. The warranty card is applicable to the old model.
