I bought 3 rugs and all 3 of them are problematic. When you screw them, the little one drinks and as soon as you put it in an upright position, the milk runs down from the side underneath where you screw it!! They are all new!! I do not recommend it!!

We have two of them and both have leaks if the small one is tilted. Also, sometimes it cannot suck and needs to be unscrewed and screwed back in order to hold better, probably the plastic underneath needs a good cleaning.

Very good and convenient. When the child turns it upside down, not a single drop spills. Only once it happened to open due to a fall, resulting in the juice spilling, but maybe we didn't screw it on properly.

We used it with milk, so the lid didn't clean very well.. easy and fast... but it will be great for water!

Everything is good but it unscrews very easily, resulting in the contents spilling. I expected more from Avent...

It's perfect!! It doesn't leak a drop even when I hold it upside down. It has fallen on the floor several times but it doesn't get damaged! The baby accepted it immediately. We had another one with silicone which he would bite and constantly make holes in, resulting in having to buy a new replacement every now and then. This one is made of hard plastic and no matter how much he bites it, it doesn't get damaged. I would definitely buy it again.
