I heard great reviews about CamelBak, and how it's lasted years and the such, but my didn't last past a year.
1. The straw leaks if it's on its side
2. If you don't have access to a dishwasher, like if you're living in a drom, then mold starts to grow on the inside of the rubber suction part
3. One of the plastic pivots that move the rubber suction part back and forth broke, and caused it to leak even more
The plastic bottle in itself was very good and durable, but the problems were mainly with the top portion of the bottle.
It's not a bad buy, but these are just some of the problems I found with this bottle.
