I have been on an elemental diet. Protein powder is in powder form. When I put the protein powder in the blender bottle, the protein powder becomes too full. This protein bottle is really airtight. However, you must make sure that the clips fit tightly. You may hear a click, but it’s not very loud. I find it difficult!
I like that the protein shaker has no odor after washing, because some protein shaker bottle can smell the contents inside. The size of the mouth is perfect for me. The only problem is that the electric protein shaker is a little too big for the car cup holder. It really could be one. But that’s okay.
A plastic sheet is obviously useful, as a portable blender bottle is as easy to use as a blender.
