Query: Music worked fine, everything else not so much...

This was my first MP3 player. Unfortunately didn't work out so well. I had no trouble initially getting songs on the player, the playlist feature worked well. Unfortunately, after about 20 uses, the sliding power/on off button came off. Because there's a tiny piece which connects inside the player, there was no way to reattach and have work --- so I had pay $30 plus shipping to send and have a new unit sent out. My second unit, I only maybe used a MAXIMUM of 10 times before the screen went black. I was able to remember how to "navigate in the dark" to get to my playlists, but obviously not very ideal. In lieu of sending back a third time, I cut my losses and purchased another brand.I had no problem with the sound quality or ease of use of this player -- actually my new player's sound isn't quite as good as this was. Based on my own experience, I can't recommend this player.
