I sit at my desk most days, and if you're like me it's easy to forget to get in your 2L of water every day. I personally find I am much more likely to drink if it's right there in arms reach than having to get up and go refill it. Sure, it may be better to get up and actually move, but when I'm working on a project or gaming or deep down a youtube rabbit hole it's easy to forget to get up and move. So with this water bottle I can atleast make sure I'm getting properly hydrated, and can easily keep track of how much I've drunk that day. Can't say whether or not it's the best one on the market, but it holds the water, and I can drink from it, not much more needed. I would, however, like to know whether it's dishwasher safe or not.
