The jug is very good, thick and strong and Pyrex glass. The spout allows itself to pay (this is not always the case with other products!). However, graduation is pitiful: the jug graduated 2 sides, with 500 mL of water in it, we come to 450 mL graduation on one side, and 550 mL of each other! Of anything !! So, 1 star less. It's a shame, because the product quality is impeccable to my senses ...
