Got the grey one, it definitely works and doesn’t leak like some that I’ve had in the past.
I recently got the blue one, and I love it! My protein mixes really well, and it’s a great size.
I really hate when I get clumps of protein, so the blender ball in this shaker really helps with that.
I’ve always had an issue with not being able to fully mix my protein. I’ve always had clumps left that I just can’t get to, but this blender bottle really helps with that.
