I like the design and light weight. I bought two of the 30 oz. bottles to take fuel on an extended ride. When I ran out of fuel and needed more I could only get one of the bottles open. Luckily that was enough to get me home. The bottle is great, the caps need work. I still can't open the thing no matter how much I try. I'll probably have to drill it open and reverse tap it.
