The device weighs about 437 grams, is 24 cm wide, 5.5 cm deep, 6.1 cm (measured front) and 4.3 cm (measured rear) high (cross-sectional trapezoid). It is made of black plastic. The writing on the screen is slightly bluish. Six switches (tlw. With dual functions), on the back of the main switch and connections for USB, jack (LINE IN), TF card and charging port are located (Input DC 5V) at the top. The device is edgy and has functional and not playful or even noble.
The notes to the device are only available in English and Chinese. A German instructions would have been helpful, especially since the device has a variety of functions. This multi-functionality is one of the strengths of the device.
The most important functions will be apparent to users through a combination of English instruction and tasting. Thus, for listening to music via cable or via Bluetooth. Transmission devices can be USB sticks etc., TF cards, tablets, smartphones, netbooks. Using Bluetooth button can make the coupling. The sound quality is
better than the tested carrier devices (iPad, Samsung smartphone and netbook ASUS) and a mid-range device amazingly well.
The range is classified too high with 15-20 m according to my tests. There are clear differences visible depending on the device connected via Bluetooth. With a Samsung smartphone, the range is 2-3 m and 10-12 m with an iPad. I do not rule out that there are carrier devices that actually the specified distance can be bridged. Are striking noise (crackling noise) when the devices are moved.
Clock and alarm function can be adjusted relatively easily through the dual function switch located above. The set alarm goes off even when the power is off.
The radio can be switched on via the FM button. About combining Play / Pause button (top left) and FM button can be automatically set and call the 20 most powerful transmitter in a search. It did not succeed, to intervene manually in this procedure, and to store for example only a specific station to a particular call (eg P7). Of course, any station can be set manually using the PREV or NEXT button.
Conclusion: The machine is not perfect, but the price-performance ratio. Hence a buy recommendation.
