Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Nightmare

This steaming pile of poo is on its way back to Amazon. I wish that I had thought this purchase through more carefully, given the extremes in the reviews. I got it to work after a lot of research and frustration, and after all that the streaming music cuts out every few seconds, and it unit dies completely every few minutes. I spent hours tweaking the settings before I came to my senses and realized I'd be a lot happier with my dough back.
