The new 108-key 8BitDo Retro Mechanical Keyboard grows the existing TKL mechanical keyboard — quite literally — with a full-size numpad, which will likely make the mechanical keyboard appeal more to number-crunchers, macro lovers and normies alike. The new full-size keyboard features the same retro aesthetic and extensive customisation options as its gamer-focussed counterparts, but costs significantly more money, especially considering the original is on sale.
