Task: Sentiment Analysis
Input (English): Review: i bought this product when my original ac adapter was destroyed by my dog. even at the price i paid, this was an awful product. most of the time i had to spend forever to jiggle the connecter into my mac to get it to even stay connected, and then it would just spontaneously stop charging and i have to jiggle again. it's awful! i never had any problem like that w/ my original mac ac adapter. it's gotten so frustrating that i think i'm going to take a hammer and smash it into pieces. and technical support doesn't reply my inquiries. do NOT buy this product, even if it seems cheap! stay away from it! look around on craigslist and buy a used adapter instead. this adapter is garbage 
 Polarity: Negative
