Once the built-in battery has reached 10% of its charge, the backlight is disabled and then you have 500 hours of unlit use before the MX Keys needs recharging. The amount of backlight level can be set manually using function keys, but the keyboard also incorporates an ambient light sensor that can dim or switch off the backlight to save battery when it’s not needed. The backlit keys are useful for locating harder-to-find symbols in lower light levels. Touch typists will love the definite feedback and the solid key action. The keyboard is solid and a good weight which means it doesn’t slid around your desk when typing like some flimsy keyboards can. The keys feel incredibly sturdy and aren’t spongy, even when typing quickly. The MX Keys for Mac uses a membrane mechanism for the keys so that it can have the same low profile as the kind of keyboard Mac users are used to. The backlight dims and goes off when not in use, plus it has an ambient light sensor to turn the backlight on and off depending on light levels in the room. The backlight on the Logitech MX Keys for Mac features a proximity sensor that illuminates the keys.
