I wanted a bottle that wouldn't leak in my bag, and this one really delivers. The 100% leak proof claim holds up — I've tossed it sideways in my backpack with no drips. The 316L medical grade steel inner lining feels solid and doesn't hold onto flavors. Cold drinks stay cold for ages, and warm tea is still warm hours later. The fire extinguisher shape is a fun touch, and the built-in straw makes it easy to sip on the go. The lid comes apart for cleaning, which I appreciate. Only thing is it's a bit bulky for small cup holders, but that's minor.
