Review on KeySmart Magnetic Keychain Secure Attachment Men's Accessories by Arun Siddiqui

The first day after receiving the device, a magnet was not seated in its half of the device. When disconnected, a small magnet stuck to another magnet on the other half of the device. You can reattach the magnet on the other side, but it will do it again. All that holds it together on one side is the rigidity of the plastic cylinder body and I'm pretty sure the holding power of the plastic wears off. I can't trust him to keep valuable keys. Smart idea, bad result. Useless.
