I bought the water bottle when my son was sixteen months old, as he had learned to drink water with a silicone training bottle from the same company, and I was looking for something similar that would also keep the water cool in the summer. I can say that it is perfect for this job. I had forgotten it in the car overnight on one of the hottest days of summer, and when I emptied it to wash it, I discovered that the water was as cool as when I had filled it, almost 24 hours earlier. Overall, it is easy to clean (it has its own brush for the straw) and does not retain odors.

However, the exterior of it wears out, fades, and gets scratched very easily, even though I wash it carefully with a soft sponge and always by hand. The spout also gets stained sometimes from different foods and takes a while to clean. I should also mention that during the first few months, my child would slightly choke when drinking water eagerly with this specific bottle, and he stopped choking after 17 months. The only reason I used it from such a young age is because it was the only bottle with which he managed to successfully drink water until he learned to drink with the others.
