Delivery fast as ever and also the packaging read easily opened.
The included user manual is sufficient, as explained the ports on the switch and the remote control itself.
For size and design just as much, size is consistent with the Amazon product description and consistent design is a matter of taste (I like it).
Now to the tests:
On switch were connected:
At the exit UHD 3D TV from Samsung
At the entrances Blu-ray 3D Player from Samsung, PS 4, 4K notebook and the old DVD recorder.
3D and 4K function properly, no dropouts and no artifacts. Once a device is switched on, the switch automatically switches to the correct input. The supplied remote control I have used only in testing, but since the switch switches reliably, the remote control in the cabinet and the switch behind the equipment is installed.
Now that I have to switch some time in use, I am very satisfied with the function, and can highly recommend it.
Now a small drawback, or whining at a high level:
The power supply unit. Since the switch 5V / 2A requires, in my opinion, a USB charger with 2.1A output is sufficient. So I could connect the Switch directly to the USB cradle and spare me the place in the connector softly. Also, the power supply could be realized with micro / mini USB.
