Great filter, made me want to drink more!

Best filter ever. Just got back from a backpacking trip in southeastern Utah. Not much water around, have to plan your camps near various springs. Normally I would pump using the MSR MiniWorks with a reliable field serviceable ceramic filter cartridge due to potentially nasty water I would have to use deep in the desert. I took the MiniWorks along (1 lb) since I had not used the Autoflow Gravity Filter (14 oz) yet and wasn't sure about the filter clogging up. I thought it may last for a few days and then I would be pumping ...and pumping. But NO! I filled the red bag up with approx 5L of life giving "water" and started filling up my 1L Nalgene which took only 2 mins 10 secs. My buddy was psyched now that we basically had a water faucet, totally convenient. We would filter approx 8 liters a day and the flow rate was maintained until about the 25 liter point, when it took 2 mins 30 secs ....bummer! We felt like we were cheating! It was so easy we would just guzzle and cook with the 0.2 micron filtered gold whenever we wanted, no more pumping! No shoulder muscle pain after 5 days! It worked the entire trip (6 days) with no filter clog issues! Almost made me wonder if it was really filtering. Sure, I had to figure out the removal of bubbles around the filter, the backflow process too. No stress mon. Get it ...best gear upgrade I have had in years. And don't bring your MiniWorks as a backup ....ya don't need it.
