fantastic - after some trouble

When I bought this filter a few weeks ago, I tried it out at a stream near my house and it was amazing. However, it became less amazing about six hours into an eight day camping trip. At first it was just difficult and slow, but later the flow reduced to a trickle. I was backflushing every 6-8 liters (which is really easy and not much hassle at all once you've done it a few times - just make sure you have a nalgene or platypus. Klean Kanteen also makes an attachement which should work.) Anyways, we ended up boiling water for the last four days. When I got back, I called MSR about it. They asked for my name, address, and the serial number, and then sent one out right away. The call took about two minutes. Now my hyperflow is working perfectly. If you want to be on the safe side, you might consider buying this from a smaller camping store, because they would have the most current ones (having to restock more often). If you decide to buy it on backcountry, just make sure to call MSR and check that serial number. It really is a great little filter; It comes in a double sided carrying pouch with simple instructions. I have done dayhikes with just this - no water bottle - but that was mostly for the fun of it. Like having a water fountain in your pocket.
