The water cooler at my office is a bit of a walk away from my desk so I wanted to get a bottle to keep at my desk. This fits the bill perfectly. The spout is big enough to for the water into a glass, but not so big it's uncomfortable to drink from directly. The one-hand opening mechanism is Useful goal can be a bit 'stiff' at first. No plasticky taste, qui you get with a lot of cheaper sports bottles. Great product overall.
