I can't say enough awesome things about my BKR bottles. They are the perfect size, they come in great colors, and they're glass, so I'm not getting cancer every time I fill my water bottle up. You can put essential oils in your water without compromising the quality of your bottle, and the opening is the perfect size not to splash on yourself. I understand that it's not awesome that the lid isn't attached to the bottle, but because of the size of the mouth, the bottle doesn't spill easily if you're holding it. Also, the company sells perfectly sized brushes so you can clean the inside of your bottle, or if you use it exclusively for water, you don't have to be so worried about weird stuff getting inside. Everybody should drink water out of a reusable bottle, and that bottle should definitely be a BKR.
