best hunk of metal I have
What can I say. This thing is bombproof. A little TLC after every backpacking trip and it will take care of you when you need it. Works well even in pouring rain. High altitudes are no problem. COLD weather has no ill effects. My only gripe is it gets a little black soot from priming, but that can easily be cleaned off. I wish the pump was not plastic but it works after five years of abuse.
