The bottle has a good idea regarding the cap - hence the only star - but the execution regarding the container itself is very lame. I left a bottle in the complaint, I hope I can get it returned or exchanged for another product. I think a thermos bottle in which the boiling liquid cools to hand temperature during the night is defective. If the bottle is only intended for keeping cold/hot liquid cool/warm for a few hours, there should be a separate mention of this and placement in the store somewhere other than the thermos bottle shelf. The same insulation can be achieved with, for example, advertising neoprene covers intended for cans. €45 for just a bottle of drink is a pretty steep price for a poor person.
