"GARBAGE - VERY EXPENSIVE GARBAGE" - Review of MSR HyperFlow Microfilter

Do not buy this pump. Three of us used it on a seven day trip. Each of us experienced the same hard to pump problem that other experienced and frustrated hiking brothers have shared. Although we pumped from clear clean sourced and followed the instructions for backflushing to the letter this pump FAILED with a capital F. It didn't work and we all ended up using another brand that one of our fellow hikers brought. MSR owes many of us trusted customers an explanation and refund.
