Review on 🔒 Certified Stainless Key-Bak Retractable Carabiner by Isaac Maze

The locking mechanism does not work. It features a raised symbol to indicate that the lock slides to hold the wire in place but does not move. I think I can use it without stalling, but as an engineer testing systems on the mobile launch vehicle for NASA at Kennedy Space Center, I want to make sure my gear is working before working on the rocket.
