I have to say that I really really really like this water bottle. Not only does it keep cold drinks cold but it also helps keep your hot drinks hot. I am able to bring coffee to work with me in the morning in this bottle and have it stay relatively hot for a decent amount of time. I do notice a bit of condensation on the bottle with the cold drinks, especially if you use liquids that are extremely cold or you use a lot of ice cubes in your drink. I plan on ordering another one because I want to see if there are any inconsistencies as there seem to be (according to people's reviews). I received this product in exchange for my honest review.
