Task: Sentiment Analysis
Input (English): I used it twice and the battery dies in half or less of a day. Maybe I'm not using all the features right? It's difficult to understand what they mean when you need extra buttons. But that's okay, I'll take it back if I have too. It worked great for six months. Then suddenly everything is slow down or stops responding even with full battery. And then only half of my buttons work.
Output (English): Bad review
