Ex Input:
Adapter worked flawlessly for six months, then became intermittent. Seems to be broken or shorted somewhere near the connector to the computer. Even the ridiculously flimsy cord from Apple lasted longer than six months, so I can't say I'm pleased. Macally says they'll sell the connector cable separately for $17.00 which is not much of a bargain.

Ex Output:
Negative

Ex Input:
I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.

Ex Output:
Negative

Ex Input:
Works very well and at a very reasonable price. It is built a lot stouter than the Apple power supply it repaces and at less than half the cost. You might miss the light on the plug but it work fine witout it. I doubt that the light is worth an extra $50.00.

Ex Output:
Positive
