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. Also, you do need to be careful and take apart the lid completely including the little silicone stopped in the middle to let it dry every now and then, or the bamboo will mildew -- learned that the hard way. Overall, though, I love it!
