Review on 🔌 MT-VIKI 4 Port Hotkey KVM Switch HDMI with 4 USB Cables & 4 HDMI Cables 4K 30Hz and 2 USB Hubs for U Disk and Printer by James Mayberry

Power, 1A" was defective upon delivery. Its output was 4.74V (under spec) NO LOAD, and the main KVM switch box (no remote) alone could not reliably power a keyboard or mouse.The voltmeter on the USB port only shows 4.25V when the keyboard and remote control are first connected to the KVM.But after 1 week the remote switch failed due to a short circuit. When I plug in the remote, it doesn't light up, KVM dims and doesn't work.(The USB port voltage drops below 1 volt even when I use my third-party 5V 2A power adapter.) The KVM works with a 3rd party power supply when the included remote is never plugged in. This fact prompted me to test further to verify functionality, reliability and image -/Check sound quality. until I missed my return window by a day. The only issue with this kit's main unit is that it requires dozens of reboots and software updates to make it work with two desktops and two laptops. (All Windows 7 and 10 in my testing at the moment; Linux testing is about to start.) This requires patience and trust that computers and connected monitors, keyboards, mice (and other devices like a camera) will eventually interact with each other and everything else. Video quality (1920 x 1080) is good with perhaps a slight drop in quality. The sound quality is also good, but can vary slightly depending on the hardware and "normal" settings/routing. In Windows - Control Panel - Devices there are many settings/options and new devices when plugged in, doubly so when I use newer laptops via docking stations connected via USB-C.
