The Das Keyboard 5Q is the ultimate tool that keeps programmers focused on creating software and operating at the highest level of concentration. No more unwanted interruptions. Instead of relying on snooze-able, momentary alerts from different devices, Das Keyboard 5Q ambiently tracks the status of the most important information, in a simple color-coded system. For example, if your website is down or you have been assigned a new task, or if the software build fails, the Das Keyboard 5Q will change color and let you know.
