I chose it for its display xxl actually very practical, but the brightness is too strong even at its lowest setting. Anyway, there are only two positions: "brilliant" or "more bearable" ... Moreover, it is impossible to adjust the sound volume in the recovery position while it is possible simply listening radio. The alarm clock is frankly tonic and sound automatically increases very quickly. Very effective for getting up very very quickly but ... I had to put something in front of the sound output to choke a bit. In fact, from the size of the display, I am not satisfied with this product.
