I'm very pleased with my copper drinking tumbler. It's very bright and shiny, and the hammered pattern is attractive. It's a convenient size and feels comfortable to drink from. It does make water taste slightly different, which I think is a nice taste. I don't want to wear a copper bangle and I'm hoping this will be a good substitute to help my aches and pains. Copper has such a good reputation for helping arthritis that I feel this is worth a try, but even without the hopeful health benefits, it is still a pleasant drinking vessel.
