This little water bottle is great! I love that it's plastic free, I love the design, and it's very easy to wash and keep clean. The seal on the lid holds well, and it's a nice manageable size while still being a good amount of water. It took me a little while to adjust to drinking out of a metal straw -- I'm not keen on metal-flavored water -- but the metal tinge is extremely minor and I got past that pretty quickly. My only complaints are that it's basically impossible to lay it on its side when it's full, which makes it a little harder to transport than previous water bottles with screw-on lids, and also it would be nice if it had some kind of sleeve for a little extra padding, since the pure glass does make me a little nervous. Overall, though, I love it!
