Honest little switch and worth the amount it is sold for.

- Personally, I used it with Ugreen displayport 1.2 cables for 4K/60fps, which is the same as the switch.
- It does what it promises.
- The rated cables can be up to 2 meters long for input and 3 meters for output. I placed it near the screen, so I used 2 meters for input from 2 computers and 1 meter for the output to the screen.
- Power supply connection through the usb-c port is mandatory, otherwise the switch does not turn on.
- I used a usb power consumption meter in series and noticed that as soon as the displayport cable is connected, the amount of power drawn from the usb port drops. Nevertheless, the usb power supply is still necessary.

- The reason for the 4 stars: it does not retain memory and goes back to position 1 after each power reset. It also does not automatically detect the computer that is currently operating. This means that it needs to be placed within reach of the hand.

Overall, I am satisfied because it is very useful for a screen that only has one displayport port.
