“I like that the agitator doesn't make any noise. Snd I like the size of it. On the other hand, the bottle gets slippery from the condensation.
An insulated shaker as the same size, would be great addition.”
“I have used just about every type of “mixer” / “blender” bottle out there and these are by far the best!!! The size is perfect, the quality of the plastic is like no other and the removable mixer thing is so much better than the balls! I am obsessed with these and bought one is every color but the black! I think I need the black ones for my boys so they stop stealing my cute colorful ones!!”
