Bests & Worsts Reviews from Amazon

So the bottle looks great seems sturdy as all hell and keeps your water cool for the day. 36 hours is a stretch you would have to fill the entire thing with ice and have a tiny bit of available water to pull that off. Also of you are changing elevations be prepared to have water everywhere. I was driving up the grapevine which connects backersfield to LA and I went to get a drink. More water came spraying out of that straw than I thought possible. I was completely soaked, it looked like I pissed all over myself for hours. The water coming out of the straw damn near killed me as it splashed into my eye and rendered me visionless as I was driving. On the plus side it was a hot day and coming from the coldest bottle the water was still ice cold. Not sure if it's really worth the 100 bucks, but I would buy it again even after it almost murdered me.
