This is the perfect carafe for one person. I can no longer imagine my desk without them. I enjoy preparing the carafe with water in the morning and refilling it throughout the day. I've definitely been drinking more since then. The carafe also has another great advantage, namely that it is super easy to clean. Things are often not used that often because you don't want to go through the hassle of cleaning them. You notice and see the special quality of the glass.
