I had received my Bryna LE as a Christmas gift and never got around to using it until now. The very first shot all the CO2 released. I figured I did something wrong and installed another CO2, same thing happened. After several failed attempts and numerous CO2, I contacted customer service. I spoke with Sam who was very personable and understanding after a brief conversation she had emailed me an authorization and return label. Within a few days I was advised via email that my LE "O" ring for the CO2 cylinder was defective and repaired and shipped out. Not only was the job completed quickly, but they sent me replacement CO2, doing that showed me the genuine concern for great customer service and support of their product. Thank you
Recommendation: Highly recommend the "Bryna Defense"
