24k platings that we've been seeing definitely wear, and pretty quickly. That doesn't
mean that someone can't come up with a thicker 24k plating that will last longer.
Some of the '24k platings' will wash off with solvent.
My experience with lifetime warranties is that they know they'll get few returns, so
it is worth it to replace the few that do get returned. That does not mean that the
plating is any better, just that they warranty it. Not unlike the money back guarantee
you'll see on TV, but you pay the shipping and handling fees, re-stocking fees, wait
on hold to get a return authorization etc. etc. Yes, it is guaranteed, but they'll make
sure it isn't worth your while to do return it. It's a game of numbers.
Not saying that's what is going on here, just pointing out that 'lifetime warranty'
doesn't mean it will never wear.
My main problem with the finishes isn't even the plating as much as the poor finish
underneath the platings. This can also cause the plating to fail.
