I bought 2 of these bottles. So far they do what they say and even leaving them in a hot car you can still have a very cool drink. However, I'm not happy with the quality of the paintwork on the outside. We are not careless people but in the short space of a couple of weeks both bottles are pretty scratched. It is obvious that a bottle lie this is going to be taken out and about. We took them to the beach and they were in and out of bags and on the sand for a while. I think others may have had this problem as I now see you are making powder coated bottles. They are good but expensive for something tat looks tatty so quickly.
