Before we ordered this set, we had a collection of miscellaneous plates and bowls from other sets.  Why?  Because everything we bought we ended up chipping - even some of the higher-end stuff that we've bought.  
We've had this set for 6 months - not a single chip - even with a 10 yr old and 11 yr old regularly loading and unloading the dishwasher.  Another bonus is that the plates don't get hot in the microwave.  
Today I'm buying another set.  This is our new standard.
