I bought this pump to go with me on a 5 day hike on the Appalachain Trail. This pump performed flawless. It was really light wieght, and I stored it inside the CamelBak holder (not in the bladder). Its mesh bag makes this pump really nice to transport, and easy to pack away. The pump was easy and quick to use. The line is a soft material, so you have to make sure it doesnt kink - although it still works, its just slower. I used this pump everyday, about 3 times a day to fill 3.5 liters. I wont leave home without it.
Pros: Light wieght, comes with mesh bag, easy to use, adjustable float,
Cons: sometimes hard to work with 2 hands, line crimps easy
