Creative Labs Nomad II MP3 player. Do not buy this product! I initially bought this unit because it had "name" & several good reviews.  You can imagine my dissatisfaction when the actual product arrived & did not live up to expectations. Ok, the first Nomad unit that I received was a total failure. Nothing worked. The rechargeable batteries could not be recharged, the "docking station" was "FUBAR," and the player simply did not work. OK. Trust the company.  Send the unit back & get a new one. Did that. Got a new unit. Guess what? Worked for four hours & then stopped, shut down, quit, for no identifiable reason. Frustration. Conclusion. Do not buy this product. For whatever reason, design, quality control, whatever, this product is FUBAR.  It is totally unreliable! Do not buy it! Do not waste your money!
