Task: Sentiment Analysis
Input (English): Review: After two go bad experiences with this product, all I can say is do not buy anything from Macally, at all. The first AC adapter for my G4 laptop went bad within 6 months and the second AC adapter was shot in less than five. When I say this product is junk, I'm not exaggerating. Basically, when you started to hear a high pitch whine, that was all she wrote. Within a week or so, the unit was dead. After the second one went dead I contacted Macally's customer service representative which was an exercise in futility. I was stonewalled at every turn. I finally just asked them to send me a new unit and they demanded proof of purchase. I then offered to send the old unit in but they wanted a receipt. All of this for a twenty dollar AC adapter. I'm sure this guy has a lot of practice giving his customers the shaft by virtue of the other bad reviews for this product. Do yourself a huge favor and do not buy anything from Macally.
