About three years ago, we had done quite a bit of research on water filtration systems. We liked the gravity fed system (less work, more relaxation time) and decided to go with the Platypus GravityWorks 4.0L Water Filter System for use on our backpacking trip.
On that first trip, our system supported five of us and on some days, we were filtering between 20-40 liters of water. We have filtered all types of water: stream, lake, pond, and even brackish, all with the same result. Occasionally, things slow down a bit, but if we just follow the directions and back flow it, everything works fine.
Five stars all the way on this device!
