I own this keychain and I use it EVERYDAY !! It keeps all of my keys straight,but, it keeps them all in order,AND,IT DOESNT BREAK !! Ill do the same thing every day,Lock my room door,Lock my front door, then take mass transportation to get to work. THEN, I go to work . After that, I go through my work day where most of my fellow coworkers DO NOT have any kind of key to the back door, but , I do! !! Then, I do it and most of my coworkers have been undisturbed. Then ,most of my co-workers will go on to work,where most of their trash will be disposed of. Hope you enjoy this ?? Take care,Enjoy your flight. J.R.B.
