The belts are specific to the buckle, so when the leather belt wears out or weakens and starts to flex, your screwed.  The belt kind of rolls over for me now..being a fat guy doesnt help, but I expected it to hold up a little longer.  I previously purchased a less dressy Levi belt and it lasted a lot longer.  Interesting form factor and technology, but I don't know that I'd repeat this purchase.
