[EX Q]: I like the book Castle In the Attic because it was very adventurous. My favorite part in the book was when Mrs.Philips gave William a gift. Do you know what the gift was? Can you figure out what it is? I recommend this book because Castle In the Attic is a very exciting novel to read.
[EX A]: Positive

[EX Q]: I ordered this DVD and received a substitute I never received the DVD I ordered from Importcds (the Vendor). I contacted them and did not recieve any feedback. I can't rate a DVD I have never seen. I didn't bother to send it back because it would have cost me more that I orginally paid for it. In the future I will watch for the name of the person and/or persons I am buying from. I thought they were a good company. I understand a simple mistake but, to not get a response at all is not good businees sense. I spend hundreds of dollars a month on Amazon.com building my DVD collection. I guess I will be more careful in the future.
[EX A]: Negative

[EX Q]: The picture seems to show a somewhat robust rod, but what you get is a very thin (1/2") rod. When exteneded to near its mazimum length it becomes very flimsy and will barely hold my small shower curtain without bowing in the middle. I would have expected a little better for the price and the intended use. But, it works and it's black.
[EX A]:
Negative
