MagConnect (Quick Disconnect Keychain)
the magnet could be stronger when I pull them out of my pocket more than once the magnets pulled apart luckily my car key fob and key were still in my pocket
If I could give this thing 10 stars I would! I bought two so I could exchange car keys for the car I decided to drive that day. Works perfectly! Easy yet has never has come unattached without my consent! Right on!
