This is a good MP3 player for people that are only looking to store a small amount of things on the device. If people want to get more storage, but still have the small device, they can get micro SD cards that will allow them to put a lot more music on the device. Sound Quality Sound quality will depend on the recording that is being played through the player, and the type of headphone that a user is using will make the sound quality different. The bad thing is that the device does not make bad recordings better automatically, so it is not perfect. Performance The performance is very good. Most of the time, content can be heard very well, but sometimes, the volume cannot go high enough to be heard. Battery Life The battery life is about 10 hours for moderate usage, and that is very good compared to similar MP3 players that are on the market. If a user is only using the device on low volume and with the screen off, the battery will last for a long time. Durability This device is small and very compact, so if it is dropped, it will not get damaged very easily. The screen is plastic, so it cannot shatter, and if is very difficult for the buttons to get broken off. The clip part on the back is the only part that can easily get broken off. Ease of Use This is very easy to use because you just choose what you want to sort your music by (Artist, Addition Date, Album, Song), and you use the 4 directional buttons, and you go down the menus and choose what you want to listen to. Design I like that the device is very small, and that makes it difficult to break, and it makes the device very simple. There are 6 buttons, and that is all it needs to function properly. The clip on the back is very good for working out, and doing anything where you are moving. You can just clip it onto your clothing.
