Man was I disappointed to find one of the cups chipped after a few weeks of use.  Ive searched for different color glasses to minimize the amount of glasses that we use and I was happy to find these but the quality isn't to the standard of other cups that I've purchased and had for years with no chips.  I should have taken heed when I read this happening to another person reviewing on another site.  I was just hoping that these would be a little better even though they looked exactly the same.
