Title: Defective! Review: Router was defective right out of the box. Asus customer support never told me exactly what may have been wrong with it, they just recommended that I return it after a short troubleshooting session. It just would not communicate with my modem.That said, Amazon's returns process earned a 5-star rating in my book. I thought returning would be a headache, but the whole process was swift and painless, with the money being refunded instantly and a 30-day window to ship the item back.Bravo Amazon. Asus... not so much... Does this product review convey a negative or positive sentiment?

Title: not good enough Review: The teleconverter is not sharp enough, especially for a high-def camcorder. I made a test: took the same shot with the converter and without; I blew the second one up 4x in Photoshop. There is not an appreciable difference. Therefore it is not worth it. I would not buy it again. The reason I did not return it is my lazyness. Does this product review convey a negative or positive sentiment?

Title: Disappointed... Review: I was disappointed with this mystery. I've read quite a few, but I found this story a little dull, and the characters not particularrly strong. Does this product review convey a negative or positive sentiment?
