HDMI Switch 3-in 1-out 4K60Hz HDCP2.2 HDR

Purchased in March 2021 and used for just under 5 years, I am selling it because I no longer have a use for it due to moving. Although it's a product from an unknown manufacturer, it operated without any particular issues.

The following is quoted from the Amazon product page:

① Improved Operability! Button shape has been refined for a better fit to your fingers, with significantly improved tactile feedback and excellent durability. Luxurious new design. ② New Feature Added! The newly established AUTO SWITCH button allows for one-touch ON/OFF of the automatic switching mode, preventing unintended signal switching and is ideal for fixed device usage.
HDMI Ver. 2.0 Switcher: Data transfer bandwidth expanded to 18Gbps, supporting 4K@60Hz resolution, HDCP 2.2, HDR, and 3D high-quality video. Backward compatibility with previous HDMI 1.x versions is ensured.
3-Input 1-Output Switching: An HDMI switcher that allows you to easily switch and output video and audio from 3 HDMI devices to one high-definition TV or projector.
Wide Compatibility: Compatible with Nintendo Switch, PS3, PS4, PS5, Xbox, Fire TV, PC, DVD players, HDD recorders, etc. (※For PS4/PS5, there are cases where they may not operate due to insufficient power supply. If necessary, please supply power to the external power port on the side of the unit.)
Automatic & Manual Switching: The switcher detects the signal when a connected device starts up and outputs it. This is convenient as there is no need to press the button on the switcher itself. (※Operation may become unstable depending on device compatibility. Some recorders may output a signal when recording starts, causing the screen to switch suddenly. We recommend selecting the appropriate switching method based on your usage environment.)
Remote Control Included: The drawback of manual switching is having to move to press the switch. With the included remote control, you can switch from your seat while maintaining stable manual switching operation!
External Power Port Included: It can be used without an external power adapter as power is supplied from the HDMI devices. However, since the power supply from HDMI devices can sometimes be insufficient, an external power port and USB cable are included for stable operation. *AC adapter sold separately.
