I use a Katadyn BeFree. I actually used to use a Sawyer Mini. But I always HATED the squeeze bag that comes with it. Also, you have to squeeze hard and the flow rate is low. The Katadyn BeFree has a much more pliable squeeze bag that is easier to fill. And it flows MUCH more easily than the Sawyer Mini. On the other hand, I hear it plugs up lore quickly. But I am willing to replace my filter more frequently if need be.
