The product comes in a perfect and clean packaging, this is serious.
The package contains a plug transformer europe standard 2 points that can be adapted to any voltage between 100v and 240v.
No supplied HDMI cable, to anticipate so.
Side operation is simple; it connects the entrance on the middle socket (surrounded by white) and has 4 outputs (2 distributed to the left and 2 on the right as in the photo).
Henceforth we connected an output, the operated system. The opposite front LED indicates the function plug.
With each new connected socket, the system automatically reconfigures itself and suddenly, it's normal operation
No worries met except for a -well projector détecté- but would not display the image.
And some problems encountered with HDMI cables -> HDMI is capricious. This problem was resolved by changing the cable.
Without questioning the product.
Overall I recommend this splitter. If a problem occurs first check the cables replacements.
