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: This bed is great. I use it everyday for my little.So far its still inflated and very comfortable.Recommend it for anyone who has a guess or personal use.I especially like the pump, how its connected to the bed andcan store-it inside the bed.
Example Output: Positive

Example Input: This movie was the epitome of, well, everything wrong with movies. It took the premise of adapting Homer's literary classic and completely butchered it into this...osbstrocity. With acting that would pale in comparison to an elementary school play, a script that would make Ed Wood blush, and some of the words special effects ever, it truly makes me sad for humanity.The one good point is that it makes for some great "in" jokes. Telemakhos's double spear throw has become a running gag at my school.
Example Output:
Negative
