I am a letter carrier and my badge takes a beating every day. This ID holder had good tension, I am using my badge which came in a hard plastic case that I slipped into their clear holder and I also have a carabiner on it too and it says up. One day, I did not have pockets and had to attach my truck key to it intermittently---that was the weight deal braker because it kept getting pulled down. But that was an extreme case, and it went back to normal after that. So it's a great product and I am glad I have 2 for a back-up.
