The concept of One Green Bottle is not a new one, but I think they do it best. I’ve had my bottle for a while now (an 800ml blue one) and the main bottle has lasted the test of time. I use it every day, filling it up 4-5 times a day. Not only does having such a lovely reusable bottle motivate me to drink more water, it also makes me feel a tiny bit better about our climate crisis. The lid and straw have to be replaced more often than I thought, but this makes sense considering how often I use it! The lid and straw combo stops sucking water up properly after a few months, sucking more air than water after a while- I’m not sure if it is the connection between the straw and inner lid part that’s the issue or the lid itself. This small issue is just a tiny flaw though; overall, the main body of the bottle still functions properly and actually looks good considering how often it gets chucked about. I wouldn’t buy a bottle from another brand than this one, that I have to since I’m pretty sure this bottle will last me years to come.
