First aesthetically speaking, this device is "in tune with the times" with nice rounded curves under and lacquered colors and moir money that makes it comfortable to watch. Good agreement, this is not what is expected of this unit to the base but it does no harm it is beautiful! The ergonomics point of view, the various keys are easy to achieve, however, we must recognize that the handle a little embarrassed to see. Otherwise, the handling is easy and simple and clear instructions it can be used to full capacity. Oh, read the leaflet helps a little anyway!. Concerning the quality of the reception, I qualiefierais "good-average". I think the antenna is a bit short and thus its ability to accurately capture the FM band is slightly reduced. Having a USB port allows you to play many types of files (MP3, among others) and the sound is very good. This is great that's what we want. The audio jack allows you to play music files from any readers with a 3.5mm audio output (Plus the cable is supplied) The sound is also impeccable (obviously if the original file is correct all the same). I have no idea of its autonomy on battery but since it has a built alimentaion which also allows it to operate directly on 220 V (the cable also provided) I will say that it is usable everywhere. The only regret, it does not display the name of the stations, it is not normally equipped with RDS. You can not have it either. Anyway, I do not regret my purchase. The price / quality ratio I attribute to them is: is 4/5.
