Example Input: We got our PowerBook in July of 2003 and had to replace the Apple adapter twice. I finally got fed up with the flimsy cord and purchased this Macally PS-AC4 adapter and I am very happy with the quality of the product. We've been using this for months and the only complaint (which is why the 4 stars and not 5) is that we miss seeing the little light around the end of the cord that plugs into the PowerBook that indicates the charge status (the one that glows orange or green). I would highly recommend this replacement to anyone, as long as you can live without the status light. At this price, it is hands down a better alternative to the delivered cord.
Example Output: Positive

Example Input: I bought these. After two uses (the first being a french vanilla cake, and the second fudge brownies), they stained from the brownie batter and will not come clean. I figured these would be better quality, since they ARE kitchen aid.
Example Output: Negative

Example Input: A GOOD VIDEO BUT IT DID NOT HAVE ENOUGH INFORMATION THAT I COULD USE WITH MY CLIENTS.A HELPFUL OVERVIEW OF WHAT IS POSSIBLE
