A friend of mine uses these in his game, they are okay for an entry level chip, the glitter ring is not really my thing but some people like it. As far as stacking, feel and sound, well.... You get what you pay for.
I have also heard really good things about the Monaco/ Poker Knights/ Showdown chips at the same price point, plus the 25k chip makes more sense than the 10k of the Monte Carlos.
Get samples! Even if you are only planning on ordering $100 worth of chips, get samples.
