Review on 💻 Effortless USB-powered Epiphan KVM2USB 3.0: Your Trusted Crash Cart for Seamless Connectivity with Any Target Computer by James Hodzic

This is the only emergency device I've found that connects to the client (master) computer via USB 3.0. I tried another company's USB 2.0 device and Epiphan just screwed it up. It's *much* more responsive and offers a moderately accurate rendering of the host computer's GUI. On a competitor's USB 2.0 device, the latency for mouse and keyboard actions was about 2 seconds and the video was blocky, jumpy, and blurry with very inaccurate colors. The epiphanic latency is there, but much less noticeable. And it plays the host's video with sufficient fidelity. It's far from a perfect copy of the host video, but it's not bad. If you just need to use console/command line tools to manage host machines, one of the cheaper USB 2.0 rescue carts might be fine. But if you're running Windows or other GUI tools on the host, I think you'll be very disappointed with anything less than Epiphan. Despite my praise for Epiphan, I must provide some context. It *does* not *deliver* a pixel-perfect reproduction of the primary display. No way. To my knowledge, all crash cart devices use frame capture technology to translate the host's video to your client computer's screen. The alias is inevitable. The loss of sub-pixel control is particularly noticeable, resulting in a sort of prismatic effect on text and line art. You don't want to be involved in long work sessions with some sort of ambulance. You would be much better off with Remote Desktop Connection or Xterm if either of those could be arranged. But if it could be arranged you wouldn't need an ambulance. The Epiphan device is expensive; it cannot be denied. The rest, even at half the price, aren't cheap either, and are much less useful. If you need an ambulance, this is the one for you.
