Keychron K10 Full-Size Mechanical Gaming Keyboard (Open Box)

First, the good. This is one of my all time favorite keyboards to type on. You'll never want to go back to a plastic / spring loaded plastic keyboard again. The feel of the surface of the keys combined with the feedback response is outstanding. The 3-height leg adjustment is a welcome feature. Now, the bad. The only reason I purchased this was to switch among computers and have only 1 keyboard. Well, well.. Here's the scoop on that. First, MAC. Good luck getting the Mac to see the keyboard. When the Keychron shows up in the available devices, the Mac can't connect to it. (I use Bluetooth across many aspects of my job. This is a horrible implementation.) Let's try Windows 10. Build in Bluetooth can't detect the keyboard. Ok. Disable the adapter in Windows and in the Bios. Purchase a brand new ASUS BT 5 dongle. Good news, it can see the Keychron. Bad news, it can't connect to the Keychon. But wait there's more. to switch among devices you have to remember to move two toggles on the side of the keyboard. One is for Windows or Android, and it's marked as wao0ithjgae;rogkj (See the photo, which I've enlarged and sharpened in Photoshop just so you can read it). Or LSKDFLKDW, which is likely Mac. You also have to choose among: BT, OFF, or Cable. Those are marked ast ## 90D* and C0ek2. Ultimately, I use the cable and connected to the PC. I love the keyboard very much, but the expectation that it would actually DO what is advertised seems insane now that I've tried for 3 days to suss this out. Keychron support will tell you to restart your system, change your Bluetooth Adaper, move it closer (from the 18 inch distance from the keyboard to the dongle, or update your system drivers. ) Look if it would connect via Bluetooth to the Mac or the PC I would live with that and use the cable for the other machine. But given it can't connect with anything via Bluetooth, I'm inclined (for once) to not blame Apple or Microsoft. If you want a good wired keyboard, buy this - no reservations. If you want what they say it will do, you'll be paying $100 for torment and disappointment.
