Pro: cheap, uses SD card, AAA battery, good battery door (the door is not an electrode), button control not a joystick (I can never remember where things are under the stick, old age!), has a hold button.Here are the unforgivable cons (in my opinion): only plays continuously in serial or with one repeat A-B without remembering where it left off, not even shuffle, EQ mode is horrible the only mode that is bearable is mp3 (this is on an excellent aiwa headphone), displays track number and time left of that track - not even the track name, the button controls are good but they are on the opposite side of the SD card slot hence pressure on the buttons and counter pressure on the card when you push...This one is not as good as another cheap simple player by JWIN which has all practical functions and sounds good except for the joy stick and battery door seems to want to burst at anytime...So still I am looking for a perfectly simple digital player...
