I have bought it for my little one for summer beach and walks and activities a little heavy for her to hold it alone but it maintains its temperature well difficult to clean if the mouthpiece has been ruined by food!

While it is quite a quality product, as negatives I would first say that it does not have a lid to protect the mouthpiece from the straw, so in order to open and close it, you have to directly hold the mouthpiece, and secondly, no matter how tightly you close it, there is a small leak in the head and I consider that because of this, the initial temperature of the liquid is not maintained 100%.
