Really happy with this purchase, it does exactly what it says in the description with fantastic quality, the sync is perfect between the two TV's, the audio is really clear like it should and the picture is fantastic!
Setting the device couldn't be any more simpler, make sure you have three HDMI cables (one for the device & two for the TV's); connect your device to the 'HDMI IN' port, then connect your TV's HDMI cables to 'HDMI OUT', ones goes in '1' & the other in '2', finally connect the power cable then plug it in and your done, turn on the device & TV's and let the little box do it's job! It took me less than a minute to set-up.
I have also uploaded a short video to show you briefly what the splitter looks like when it's set-up and of course the results of the TV's (16"LED HDTV & 40"LED FULL HDTV).
Overall I couldn't be happier, so top marks from me!
