The Simplehuman Sensor Mirror Hanging has a built-in sensor. This allows the integrated light to automatically turn on when you approach the mirror. This light is just as bright as daylight and so you know exactly what your make-up looks like when you sit outside on the terrace. The mirror has a protective coating against condensation and increases 5 times. So you work in much more detail than you might be used to. This hanging model has a telescopic arm. This way you view yourself from any angle. Furthermore, the mirror is rechargeable with a USB cable. With a full battery you can use the mirror for up to 5 weeks, wherever you want. You do not need an outlet.
