This is a good product if you don't plan to use it for running. I have found that it seems to have a very bad battery connection and will 'cut out' while I'm running. What makes that especially annoying is that then the unit has to go through the 'power-up' process all over again (takes 15-20 seconds) and you're back at the first song. Of course you can fast forward to the song you were listening to, but this seems to create even more strain on the battery and sometimes the unit cuts out again. I find that the unit only operates properly during the first 1-2 hours on a new battery. From there on out, even though it might say that you have 5 hours left on your battery, you will have problems.If it weren't for this problem it would be a good unit!
