Switches keyboard, mouse and HDMI display well. I want to disable toggle by double clicking the mouse scroll wheel. Sometimes I accidentally toggle just trying to click something. There seem to be some issues with static electricity and power supply noise. It restarts from time to time when I turn other devices on and off at the power strip. It recovers, but it's a bit concerning that your screen goes black if you disable anything else. I also had static shock just from touching the keys. It's not the best quality, but it does the job for a lot cheaper than anything else I've found.
