Great little pump filter - MSR TrailShot MicroFilter

I've had this filter for a few years now and it has survived admirably a dozen or so weekend backpacking trips and countless day hikes. The size and weight are great. It fits nicely in the belt pocket of my backpack, which I've discovered I love as it means I don't have to take off my pack to fill up my bottle on the trail. My first backpacking trip with it, despite others having pumps in the group, everyone would ask to use mine because of its ease of use and proved faster in our side by side fillings. That being said it does become a good forearm workout if you're doing multiple bottles on your own. This year the filter slowed to a trickle on a long hike in which the only water source contained a lot of silt, following the cleaning instructions only restored flow for a second or two before returning to a trickle. Don't know that I made it all 2000L but its done pretty well. For hiking with groups in the future it'd be nice to have the gravity bag set-up while at camp, but I feel its way over priced.
In some ways I prefer this over the popular bag/bottle sawyer set-up as I don't have to worry about tracking/carrying a dirty bag/bottle, and don't really have a problem with shallow water sources. Also, if you do end up filtering for a group, when this has good flow, it beats squeezing out and refilling a bottle (i.e. Smart water, etc).
