This the Keychron V3 QMK Custom Mechanical Keyboard, which has its own linear K Pro Red switches and is fully assembled right out of the box without the knob. I ordered it on the original website along with some new keycaps. However, I decided to go with a more DIY approach and made another order with a barebones kit with a knob, different switches, and a switch opener so I can personally lube those switches myself. It's already too late to cancel the 1st order and I don't want it anymore since I already got another working mechanical keyboard. The other one has tactile switches and my future DIY one with have speedy linear switches. Those two keyboards are enough for me and I want some of my money back. I bought this keyboard from the original website, not from Amazon. Since the Keychron returning and refunding processes are way more tedious, I decided to resell it on Jawa since it's simpler for me to do and it'll cost me nothing. This is the best price I could offer at the moment and I already checked how much it would cost on the original Keychron and Amazon websites with shipping and taxes accounted for. Luckily, I never opened up the keyboard, so it's brand new inside the box.
