It is massive. I wanted a water bottle that would hold a lot, and keep it chilled awhile. For my needs this is probably a bit much, but I use it at work (waiting tables) and it stays prominently visible to any guest in the bar area. I DO NOT take this thing back n forth with me, nope nope...it stays in the same place all the time unless I'm going to be out of town or something. The ONLY NEGATIVE as mentioned by another is the cleaning brush is criminally too short to even be remotely useful....
