[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 Q]: This book was brand new when I received it. However, it did not arrive for 20 days after I ordered it.
[EX A]: Negative

[EX Q]: This thing works sometimes, and its cheep. Other then that I don't have much good too say about it. It uses up the ink in the expensive cartridges like water. And is so noisy it sounds like a truck going off road. I've owned quite a few cheep HP ink jet printers, and I've been disappointed by them all. I am going with Epson or paying a little more for a higher model HP. In the print world, you get what you pay for and buying cheep is a bad idea.
