The bottle itself is not the most durable, mine dropped 2 days after I got it and it exploded everywhere, the plastic looked like it got hit by a bullet, HOWEVER, I messed them, told them what was up, and that I had registered it for warranty and they got back to me the next morning, I was working 8pm-4am, and they sent me a new one right away and got it like a day and half. So, I would purchase again, and highly recommend their customer
service. The pocket on the insulation portion come in hand...
