The product is perfect both in terms of design in blue that very nice sound quality very acceptable and powerful + the many possible connections (SD card / key UBS / USB / aux / jack ...) good practices as well volume settings and MP3 control. Overall Very good quality / price ratio. The big negative is the supplied AC adapter is not compatible with the French EDF network requiring a battery charge only from a PC via USB connection !!! and the absence of color LED signaling the beginning and end of the battery charge (can not see the charge level in instant ...) I'll have to let out too much hassle to find and purchase of an adapter for this device and French sockets and that's not cool at all ... !!!
