I bought 3 sets for my new house.  Within 4 months of use we started to notice them wearing where they shouldn't.  We do not take our dishes outside, the dont sit in direct sunlight, do not sit in standing water, and we do not scrub them with anything more then a sponge.  The red around the plates are losing the gloss look in patches.  We have noticed now the rud is coming off the plates! They looks horrible! We do put them in the dishwater and our well water is not hard.  They should of lasted longer then this!
