This pretty little sippy cup served its purpose perfectly. It is leak-proof even when the abuses. By cons must pay attention to the product description which indicates that flexible mouthpieces are interchangeable with the teats of the brand ... it's true .... however here is a cup hard beak so this description not the product concerned.
Apart from this detail I am very happy to learn that cup to drink alone. The fun design is a little more black color is really like a little penguin. The handles are strong and well suited to small hands. All parts are dishwasher dishwashers.
In short, a great little cup of learning at a price that I consider appropriate.
