I only used this keyboard to test it; I'm selling it because I received it as a gift and don't need it. The keyboard is Chinese, with Brown switches from Cherry MX. It supports wireless and Bluetooth connectivity, and has multiple RGB lighting modes. Honestly, if I didn't already have one in use, the sound would be amazing. There is one issue: the letter "ذ" is missing. The seller is responsive and easy to communicate with, insha'Allah. Please don't undervalue the item. 50 SAR, non-negotiable.
