These glasses are pretty good.  The colours aren't as bright as they are shown on screen; the yellow in particular is a lot duller.  This isn't necessarily a bad thing since some people will prefer a less ostentatious look, but it was a little disappointing to me.  They're pretty heavy, which I hope will translate to sturdy, and don't feel too liable to chip easily.  They're dishwasher-safe and apparently the colour is actually in the glass instead of painted on top, so there's no reason why the colour should fade or chip over time.  They're a good size for water or mixers.  Be warned that the box is very plain and doesn't have a plastic cover over the space in the lid, so they arrived looking quite dusty.  This isn't a problem if you're buying them for yourself, but they're not exactly ready to be presented as a fancy gift.
