Query: Quality Mp3 player

I've had my mp3 player for a couple months now and no problems have occured. The Zen is easy to use and works great, along with sounding great. The one downside with the Zen is the battery life. They market the battery as lasting upwards of ten hours. In reality it only last about half the expected time. For the price and quality I would recommend anyone to get the Creative Zen Stone 1GB MP3 player.
