User Review: Platypus GravityWorks Filter System

I have owned other filtration systems before but nothing that worked this well and was this simple to use. It's light weight, clearly marked (one bag is marked clean and the other dirty), fast, and most importantly the water gets clean with no weird taste. Oh and filtering 4 liters at a time in under 3 minutes doesn't hurt either. I can't think of anything bad to say about it.
