Query: BUY ONLY IF YOU ENJOY LOSING MONEY

Everything worked great for five weeks until the stupid thing just stopped working in the middle of a song. I have never dropped it or overused it. I took great care of it, only using for 1-2 hours a day during my commute. I have not been able to turn it on since. It's totally dead. I contacted the manufacturer (after several calls and e-mails), and they sent me back to Amazon for a refund. They said, "Not our problem; you didn't buy from us. Contact Amazon." This product is #2 human waste in disguise. Buy it only if you enjoy throwing your money away.
