It loses one star because I would like it to turn a couple more times when you screw it on so that it seals a bit better. The way it screws on now, it has minor leaks when shaken unless you tighten it extremely hard. It also loses a second star because sometimes the plastic mesh gets stuck and I struggle quite a bit to remove it. I bought another one from a well-known brand, 2 euros more expensive, which I found much better in terms of ease of use and sealing.

Very good and convenient to take with you and put your protein in. The only drawback is that it is big and narrows downwards, my hand cannot fit well to clean it properly in the corners, resulting in some leftover protein from the one that was not mixed well. Maybe someone with smaller hands would not encounter this problem

very nice, waterproof and user-friendly product.. satisfied

It dissolves the mixture very well, both protein and creatine. As for its cleaning, it is equally ideal for its price. The shaker comes out very easily and can be washed in no time.
