I've been using this Klean Kanteen almost daily for about 15 years. ... It's gotten some dents and scratches, but shows no sign of losing utility.
Holds up well. one of my 20oz classic insulated bottles lost it's vacuum seal and ice was melting super fast. The plastic lid sucks
The bottle itself is alright. Light, not much else to say. The lid is absolute trash. Leaks whenever I don't tighten it enough.
In my experience, they all dent from minimal falling, they all still work fine ...
