I had it in the fridge overnight and we took it for our walk in the morning and the water wasn't as cold as it should have been. And on the first day, it fell under the child and the cap around it broke. I have bought so many thermoses, they have taken so many falls and nothing happened to them.. this one is terrible. I wasted 37€. And they assured me before buying it that it is BPA free because it is a very good German company. However, it didn't state that when I received it. My worst purchase.
