Bad – The size and fast capability to add new songs is an excellent attribute while there are a couple of major downsides. It runs on one AAA battery, meaning it has to be constantly changed. Turning the mp3 on and of more than a couple of times wears the battery down immensely. One downside of the design is that you must flick a switch in order to skip tracks etc, which can become quite annoying. Another downside is the fact that when wanting to listen to a song in a different folder, you must flick the switch to navigate to the folder the track is situated in, changing the song you are listening to, to that of the first song in each folder. You are unable to listen to one song while browsing through your other songs. Overall, the size is a definite plus but the functionality and design is a definite downside. Small, lightweight and compact Inability to view all folders on one screen (must flick through each- changing the song you are listening to)
