I am so sorry to hear of your experience with the TSA. Both Firebiner and Fire Escape are compliant with TSA regulations and should not have been confiscated. We met with TSA; they explained our carabiners are “TSA friendly.” Typically, TSA examines it, then recognizes that it cannot be used as a weapon and allows it to pass through without issue. They also told us that each TSA agent has their own discretion so if they personally felt it was hazardous, they could confiscate it, but this was very unlikely.
