Not much to say here. This is the HDMI splitter I use between my PC, FireStick and my office's 4k screen. It easily handles switching between PC and flash drive when I decide to leave some Prime TV episodes running to stream in the background while I work. When I need to work on it, the 4k resolution switches smoothly and transmits the signal flawlessly. My computer is responsive and the whole process happens in seconds (much faster even than the expensive AV receiver I have below, but that's another story. Can't speak to durability
