Recently, Keychron's high-axis Bluetooth dual-mode mechanical keyboard K pro series has launched a new one - K4pro mechanical keyboard. I am very fortunate to experience this mechanical keyboard for the first time. Let me introduce it to you one by one!

The appearance of the Keychron keyboard has always followed the simple style of white letters on a black background. There is a keyboard effect picture printed on the front, and a real shot picture of the keyboard and several major features printed on the back, but the logos are all in English.
