Bests & Worsts Reviews from Amazon

My first Camelbak broke after a year or so of daily use. I put up with it leaking a little bit, because I thought it was Just the fact that the mouthpiece that was starting to break away from the lid. But I really liked the design of the bottle, and the fact that they never smell bad when you open it. That's because the straw/bite piece design keeps the bacteria out of the bottle! I hate stinky water bottles, so I love this feature! So I bought a new one. And the first time using it, it leaked also. The bottom of my cup holder would be all wet. And if I put it somewhere, it would also get wet except at my desk at work. I finally figured it out: ELEVATION CHANGES!!! Even though I live in the SF Bay Area, the elevation of where I live is 165ft. Where I work, 3 miles away is 20ft. On my way to the gym I change altitude of a few hundred feet. My ears pop when I take the elevator to the 21st floor where I work, so even though 200 feet isn't a lot of altitude change, it's enough to put pressure on the bottle and act as a sucking action on the straw forcing out a little bit of water... Solution? Bite the nipple (or whatever they call it) after you take a drink, then the water won't be right at the tip. Now my CAMELBAK doesn't leak! Just remember to get in the habit of biting the nipples! You're welcome...
