Full Disclosure: The product sample used was provided by A4TECH.

Since the advent of the mechanical keyboards, it was only a matter of time before the market became saturated with a plethora of very similar products and options. A4TECH’s very own “bloody” division has brought forth the next evolution in mechanical keyboards, boldly daring to replace the actual switch with Light Strike technology: silent switches that operate by breaking a beam of infrared light. This not only provides the fastest possible response speed, but also adds several inherited benefits from the technology. The B740A is only one of the 15 models using the Light Strike technology at Bloody.bk_intro
