Bottom line: Great design, I wish it lasted longer, but I still love it and would buy it again.
I need 3L for long runs in the desert. In fact I usually have to refill somewhere along the way. Recently the reservoir separator completely ripped. Now the water sloshes all over the place. Bummer. But...it makes me realize how much I LOVE that separator. And I've stressed this thing to the max. Bouncing it up and down full of 100oz for tons of runs puts a good deal of strain on it I would imagine. I feel like I got my money's worth and I'd be willing to buy a new one. I could probably just get a new one too, although I don't know if I can live without it long enough to send it back for warranty replacement.
