No installation problems and no worries about the quality of the signal (one of my HDMI cables connected to the dispatcher is 15 m long).
The rocker is done automatically and if the 2 devices are switched on simultaneously then there is simultaneous projection ;-)
The case is very small, metal and food is not big heads (the size of a phone charger)
In short good buy at a reasonable price.
And as usual neat and fast delivery by Amazon.
[Update] After 3 years the splitter grilled (over signal transmitted via the box). I bought a new one via Amazon. Already the model is not the same but additionally this time, no signal is received by the video projector
In short it is a little loose this change but with the same product reference ...
