This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.

Ex Output:
Negative


Ex Input:
The book was boring and to far fetched to be entertaining. The characters were not believable and left me with wanting to many unanswered questions. The author took to many liberties with facts. All in all, I just didn't care for the book, skipped thru pages to end it so I could go on to more enjoyable reading. Amazon offers so many options and choices that I'm bound to pick a lemon once in awhile. I always read the brief description of the book before I buy but in this book that wasn't enough.

Ex Output:
Negative


Ex Input:
Pretty cheap for a Hi8 camcorder, but quality is unacceptably poor. The zoom lever is hard to operate, and when you put in a tape the mechanism makes tons of noise, really making you nervous. LCD screen is a little flaky, deciding to quit working occasionally so you have to turn the machine off, wait 10 seconds and turn it back on. It also destroyed a new TDK Hi8 tape this past winter. I think I wasted my money, and look forward to getting a Sony this summer when I get a new job.

Ex Output:

Negative
