When my wife recently gave birth to twins, i brought it to the hospital to take some video. Well, as you can expect, the camera did not work. I took it to the repair shop and they indicated it would cost $625 to fix it. Find another camcorder--this one has too many problems Is this product review negative?

I highly recommend this book to anyone - young and old. Well worth the time. I bought the second book and can't wait to start reading it. Is this product review negative?

I know better than to compare this with some of my 2.8 lenses, but, this lens held its own. The pictures were acceptable and it was easy to use. That was until it stopped working. Last week I went to Florida and was taking some pictures when the zoom stopped working, fortunately I had other lenses with me. First it would no longer go down to 18mm and then stopped going up to 70mm. That left me with a 28-50mm lens. Even at those ranges the zoom was very stiff. As I said I wasn't expecting a great lens, but, I was expecting it to last more than 6 months. I am extremely disappointed. Is this product review negative?

input with options: Title: The author neglects to inform the reader of evidence. Review: Gus Russo knows so much from his work on this case, yet he only prints what supports his theory that JFK and RFK set the covert ops in motion that led to JFK's death. He doesn't tell you about other witnesses he interviewed, like Jean Aase, nor the evidence he uncovered in his research that doesn't fit his preconceived notion of what happened. That Castro was behind Oswald is the cover story that was prepared before the murder, and Gus may believe it, but that doesn't make it true. Any historical narative that leaves out significant facts is flawed, and in this case deliberately wrong and misleading. Bill Kelly Is this product review negative?
