Bests & Worsts Reviews from Amazon

Bought this for the Nike + feature...liked the idea of a music player built into a system to track my runs. The Nike + part of this unit worked great, easy to understand and easy to use....in fact I like it so much I am going back to my old mp3 player (creative product) and getting the nike sportsband so I can keep using the Nike + features. However I have sent back two different ipod nano units due to serious problems with the music component of this device. 1) This unit does not have a way to completely shut it off...only a sleep wake button. If you do not make absolutely sure that all music is stopped, the radio is off, this thing drains battery life very quickly because you cannot fully shut the unit off. 2) The headphone jack is not very secure...using the ipod's headphones and another set of headphones from a different mp3 player the cord came out easily, when the cord was jostled sound would cut in and out making listening to the music annoying. Also becuase the radio antenna is the headphones it was constantly losing radio reception or unable to locate stations. 3) Volume control seems like it would be easy with buttons on the side..however on the units I tried the volume would lock itself to either no sound at all or set so loud I could only keep one port in one ear. I like to be able to adjust volume as I am running or working out based on the song, the environment, etc...not very happy with how difficult it was to deal with the volume. 4) When I could get radio reception and made sure not to jostle the cord (sitting down outside) the unti shut itself off after 60 seconds unless I kept hitting icons on the unit. It didn't do this when I was playing from my songlists...just in the radio mode. 5) When you want to shuffle a song while running...you have to wake the unit up then either figure out where on the screen to tap (without getting your sweaty fingers all over the unit and without tripping as you look at the screen) or shake until hopefully the device realizes you are trying to change songs (I was not very impressed with the shake to shuffle feature). 6)This device does not come with a manual...you have to go to the apple page to get the manual and download it. Customer service was useless. THank goodness for Amazon's amazing return procedures!
