I bought this water bottle for everyday use. I like to keep it with me throughout the work day so I keep hydrated, and also to supplement a workout. I love the circle hook that I can pop up for easy carrying. I am a repeat buyer. I had to buy a replacement after 2 years because the clasp stopped working and wouldn't stay shut. I think this is partly my fault because I would slam it shut instead of using the release button. Overall, I am very satisfied with this water bottle and have not had any leaks.
