A quick shout out to Blackburn Design. Props to them for replacing my Air Tower 3with a new Piston 3 pump under warranty. My Air Tower 3 gauge went bad and pump became hard to pump. I called Blackburn to see if I could get it fixed and they said they will send me a new Piston 3 cause Air Tower is discontinued. A week later I got it and love it. More air per stroke, massive gauge you can read a mile away. Metal construction. Now that's a good company!
