Very low quality and cheap mp3 player, average sound quality with very cheap design, not user friendly, it has expandable memory up to 32 gb but when you put sd card of more than 8 gb it started problems like auto off and on, lagging, when it is connected to transfer songs from computer the transfer rate is very slow you will get tired up, it is low cost chinese device, battery ends up in 3-4 months and after that it is just e-waste.
