Review on 🔁 AAO 2X1 HDMI KVM Switch - 4K 2 Port USB Switch Box with Auto-scan, Hot-Key Switch for Netware, Dos, Linux, Unix and Windows - 4K@30Hz - Includes 2 Pcs of 5ft USB Cables and HDMI Cables by Robert Berio

I've wanted a device like this with dual HDMI inputs for a long time, but reviews from everyone have had serious quirks or worse. I found this one recently and it looked better so I took a chance. Been using it for a week now, it works PERFECTLY. Easy-to-access single button on the front with a pleasant touch and clear backlit PC1/PC2 next to it. Switching between computers is very fast. Before I bought it, I was a little unsure whether the USB cables on the back looked like old-fashioned sockets. However, they work perfectly, passing both keyboard and mouse traffic to the PC through a single cable that terminates in a regular USB connection. Nice that this frees up a USB slot on the PC side. Good thing it comes with 2 USB cables and 2 HDMI cables. Nice small size - slightly larger than a deck of cards. Very satisfied!
