I like this bottle and use it every day. It arrived with a small dent so I took 1 star off. I also took another star off as you do get a metallic taste when drinking. I find it is ok if you wash the bottle daily then drink the water within a few hours of filling up. The longer the water sits in the bottle the worse the taste gets. This kind of defeats the purpose of having an insulated bottle that you can leave the water in for a long time. I do find it useful though when getting the groceries for instance. I will leave it in the hot car, come back in an hr and the water is still cold despite the outside of the bottle nearly burning your hands. What I love most about the bottle is the compact size. I have another 750ml insulated bottle that is much bigger than this one. It is also better quality and better at insulation. However, the trade off is size. The other bottle will not fit in an ordinary cup holder which is why I resort to using the Thermos Thermocafe as my go to drink bottle!
