[EX Q]: My wife is very happy with this set of dishes that we recently purchased through Amazon.com. They are everything she had hoped and expected them to be. My happiness is more related to the purchasing experience. One dish arrived broken and I was very pleased with the efficient, fast and convenient way you handled the replacement. Thanks for a good buying experience.Bob Cordes
[EX A]: Positive

[EX Q]: This thing smells SO gross, like harsh, toxic chemicals, that I can't even use it! I've washed it in HOT, super soapy water, cleaned it with alcohol, and even let it "air out," all to no avail. I tried using it and the smell was seriously distracting. I took it out of my drawer, after all the washing, to show it to my boyfriend and while i was still a good four feet away he said, "Ewww, what's that smell." I found it to be WAY too large, too, and I've had kids. Sadly, this will be going in the garbage.
[EX A]: Negative

[EX Q]: I have generally had very good experience ordering jewelry from Amazon sellers, so I ordered two of these necklace pendants, one for myself and one for my mother. Both arrived with very badly tarnished chains (about half the chain rust colored on both). In addition, the actual pendants were scratched and "used looking".
