I do love my eco vessel’s. I have several of them. They’re amazing at keeping water cool. However, I’ve never had a bottle from eco vessel that’s kept my water cold for the entire 36 hours, and if you drop them even once it cuts the ‘keep cold’ period down to only a couple of hours, drop it twice and it’s all over. For the price, I’d think they’d be a little more ‘drop proof’ I guess. Sucks to spend so much money on something and accidentally drop it once and it pretty much stop working. Overall they’re a great bottle, keeps the water cold for a period of time and eco-friendly.
