Super shaker, seals beautifully. Only when I put 400ml of water+protein, it doesn't shake well (not enough room). And when I put less, the cups are unnecessarily big.
I call this the most practical shaker! It contains 3 compartments (+one of them fits a dispenser with divided plates for supplements) for me a very good product😊
The size is just right, the compartment for supplements could have higher walls so that it doesn't mix with each other, but that's probably the only flaw
