The switch works very well and performs as advertised.
Tested it with a DSTV Pace HDPVR, XBOX 360, Samsung Blu-Ray Player and a Kaiser Baas Smart Media Player running XBMC Kodi.
Dolby digital 5.1 audio was captured from all of the devices and output via the Optical Toslink to my Amplifier and was perfectly in sync with the image on screen.
Image quality was even slightly improved and noticeable.
The device's construction is sturdy and of decent quality.
The remote feels and looks cheap.
The remote IR strength is weak and needs to be rather close and in a straight line with the switch in order to switch channels.
There is no On/Off button for the switch on the remote.
When switching between channels, there is a blank screen lag of at least 3 seconds before the new channel displays.Rating: [4 of 5 Stars!]
