I've been using the same Maxpedition Keyper for 8 years.

The paint is chipped. There is a little rust on the gate. The hook has been reshaped by almost a decade of rubbing by a split ring. It still works as good as the day I bought it.

If you need to hang something off your belt, seriously consider the Maxpedition Keyper.
