We have been extremely satisfied with this system. Of course, our 5.1 system provides the better surround sound. But still - I do not know how Sony has managed that - you're a light spatial effect, which offers more than just stereo. The menu navigation on the television with the remote control is straightforward. Installation was easy with instructions. The possibilities of use of the system itself are somewhat limited, but the most necessary works without TV. The connection with the Wireless LAN of smartphone remote was easy. The entry of Internet addresses using the remote control is botch. But if we have to be additionally installed smartphone as a remote control, you can enter here on via the normal Android keyboard. The problems with the volume of the fan I can not confirm. While it is to hear a very faint sound, but it does not bother even at low volume on the TV. We are all in all totally satisfied with the system and hope that she lives long.
