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: First of all, let me say that I am a huge Wes fan! Not only is he one of my favorite guitarists, but one of my favorite composers as well. Everything Wes played was genius, including all the music on this CD. However, this release is not worth buying.This CD follows in the long tradition of Wes bootlegs of the March 27, 1965 concert in Paris. The songs are mistitled, the sound quality is poor; the personal are not listed, the date is not listed, the venue is not listed, and the booklet is non-informative. To make matters worse the song order has been rearranged to an awful order!If you are interested in obtaining a good version of this concert buy "Quintessential Wes" by Varese Records.
Example Output: Negative

Example Input: I love this watch and get compliments on it all the time. I am an RN and have looked for years for a watch that performs all that this one does. Analog face, digital 24 hr clock,and many other features that I will never use. The best feature for me is the count down timer. I knocked off points because 1. there isn't a second hand, the seconds are digital display. 2. I'm concerned about the band because it is getting dirty and reg. soap doesn't clean it. The silver ring around the face really shows it off. Sits high and is a serious sports watch but I'm wearing it at the hospital.
