We dropped the Boehringer regulator from five feet and tested operation after each drop. A few times, we had to remove some remnants of floor tile from the surface of the regulator. Between drop 38 and 39, the gauge seemed slightly loose, so we simply tightened it and continued dropping. After drop # 50, the volunteers and Biomed Staff decided to have some fun and toss it around using a little creativity. The result was just as we expected: an excellent performance by the Boehringer product after every impact.
