Have only used the flask once yet as baby is only 7 months and we are just getting settled into solids but I expect to use it more frequently as time goes on. It's great and looks lovely, love the stickers! Lunch bag is also lovely. Only reason I've given 4 stars is that I didn't check the flask when I received it initially as I didn't need to use it for a couple of weeks, by the time I opened it I noticed that the bottom plastic bit was broken slightly, but I was too late to return at that stage. Just a small thing but I still look forward to using the product.
Looking forward to using it!
