This split keyboard design goes by the name of 'The Ultimate Hacking Keyboard,' providing the option for users to use the keyboard in a single piece, or two, depending on their preferences. Typically, keyboards that are totally straight across are not the most comfortable to use for extended period of time, since they are not designed with ergonomics in mind. Rather than forcing your hands into an uncomfortable position, the split keyboard lets your hands rest in a more natural position.
Beyond this, what makes The Ultimate Hacking Keyboard so impressive is that it makes it easy for serious computer users or gamers to configure completely custom keyboards. The keyboard boasts a high-quality build that will last about 50 million keystrokes.
