I have had this item for approx 3 months... Within those three months, the nano has locked up on me 4 times with no explanation (this has also happened to two other people I know). As I'm scrolling through the songs, the nano will simply stop responding and there is nothing left to do but wait a day for the battery to completely drain. It becomes very frustrating at the gym! SO do yourself a favor and go buy a "no-name" brand for less money. I will be going back to my old 2 gig "no-name" brand that has worked flawlessly within the past 3 years. Good luck to those who skip my advice and buy this piece of garbage.
