Example Input: You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can.
Example Output: Negative

Example Input: I just got these stockings but the seller sent me a way smaller size (A-B) than I ordered, I e-mailed them telling them about the problem and will keep you dear buyer posted. I cannot tell you about anything about the quality or color because I have not opened the ones I received.
Example Output: Negative

Example Input: What a rib tickler this film is...I've seen it twice and know that twice more at least is on the cards. Of course, I love Daniel Auteuil and Gerard Depardieu, so to have them together is pure heaven! For a quite amazing contrast, check out 36 Quai des Orfevres, a violent police/crime drama also starring both actors. Whether you speak French or not, you can tell these guys aren't just playing themselves...they are both excellent actors. See these films if you're a real, dyed-in-the-wool film buff!
Example Output:
Positive
