Review on MYMAHDI Slim 1.8" LCD Mp3/Mp4 Player W/ TF Card Support & Accessories - Black by Alex Barnes

My computer doesn''t recognize the device. There were no directions. I think it really means you have to somehow put music on a SD card and put it in. I bought this for my daughter as a first mp3 player. It doesn''t have to be perfect but I''m irritated I have to go to the store for an SD card ( a note saying that it won''t work without would be nice) and hope it fits. I saw another review that a regular SD won''t fit.
