According to the description there wouldn't be a metallic taste, but I have noticed a metallic taste. This usually occurs when my water (no ice) has been in the bottle for hours on end. However, the appearance of the bottle is nice you can tell it's well made.As far as the staying cold test here's what I have to say:-If I didn't use ice, my drink would only stay fridge cold for about 5 or 6 hours max.-I haven't tried hot drinks.-The Hydroflask bottle seems to keep ice not melted for an extended period. I could easy say ice will not melt in a 24 hr. period.Overall, I think there are other brands out there that can perform just as well as Hydroflask for the same price or cheaper (Yeti?).
