Selling my used Keychron K2 V2 Hot-Swappable. Opted for Gateron Brown switches during purchase and kept it that way. Invoice available on request but out of warranty so I don’t know if it’s of any use. I still have the box and some of the accessories with me. I don’t recall if there was a cable but if yes, that’s missing. Please check the attached image in case something else is missing.
Keyboard works in wired mode, BT, with RGB but battery is possibly dead or there’s a connection issue. I had taken it apart and cleaned it out long while back since ants got inside and few months later, it stopped working quickly on battery even after seemingly full charge. Eventually, it only worked when I put it in wired mode so battery is possibly dead. Instead of fixing it, I went through a bunch of keyboards only to discover I’m fastest and most comfortable with Apple’s keyboards. 
Otherwise, it seems to work fine. See the pictures and the typing test I did on this for a better look.
