I bought this Lyra Slider about a year ago online, and it was pretty expensive for a mp3 player similar to it. I still bought it because I thought it would be worth it. It is medium sized, pretty compact but unfortunately not as compact as I wanted it. It has a very long battery life. I listen to music all the time and I acknowledged its battery life after I listened to music nonstop for a few days! The battery is rechargeable and does not take too long to recharge, so I am free to listen to my music nonstop all the time! It has great storage, can hold up to about 2000 songs, not sure about videos. The only thing I would complain about is the slider. I find it inconvient to use and the slider makes it easier to get damaged, since I have to slide it back and forth whenever I wanted to change the song that's playing or do anything. The screen sometimes blacks out (or whites out). The sound quality is still excellent, but I wished it wasn't a slider, so it'd be more durable. Would still recommend this to people, as it has excellent sound quality and works perfectly fine.
