Review on Kosdeg Copper Water Bottle 34oz - Vintage Modern Design - Ayurvedic Copper Vessel - Improve Health Naturally with Increased Hydration and Reduced Sugar by Jonathan Clark

This bottle is exactly what is advertised. It doesn't leak and remember it's copper! Of course, dark spots appear on it, and the lid creaks when opened. It's metal on metal and there's a nice silicon grommet/O-ring in the lid. That's what makes the water taste so good, and again it's copper. So keep in mind that the bottle itself emits a metallic odor, but you taste nothing but sweet water. Just make sure you don't drop or abuse it. It's thin and sounds light, but then again, it's copper!
