Task: Sentiment Analysis
Input (English): I have bought this device on Amazon through the seller &#34;SuperGadgets4u. It's terrible. It doesn't hold a charge very long. Battery runs out super fast. The buttons stopped working after six months of use. This is an absolute waste of money. Don't buy it unless you want to feel like you're ripping your hair out. Horrible device. If anyone from'supergadgets@ua.com' reads this, go back and redesign this.
Output (English): Bad review
