7 LED backlit iPad Bluetooth keyboard

With the arrival of Windows 8, the operating system's user interface and its use of the design language drew generally negative critical responses. Windows 8's Metro UI features lots of brightly colored, interactive tiles. Windows 8 added support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Jinhongmei Electronics Co., Ltd. launching a NEW Bluetooth Wireless Keyboard support Windows 8 devices and hardware.

JHM-712 works with Windows 8 perfectly. It is in fashion and LED backlit in 7 kinds color light. Moreover, lights could be adjusted by user. In appearance, it is made in painting craft and metal brushing. 

F1-F12 keys is fuction keys support device for quick order. It is HOME, SEARCH, VIRTURE KEYBOARD, COPY, PASTE,LAST SONG,NEXT SONG,PAUSE, VOLUMN UP, VOLUMN DOWN, MUTE, LOCK/UNLOCK fuctions. And there are 3 keys to adjust lights. Press Fn button and LIGHT CHANGE button, light could be change in 7 different colors. Press Fn button and LIGHT UP button, light could be up and press Fn button and LIGHT DOWN button, light could be down immediately.

Function keys and multi-media keys are design based on ZAGG Inc requirement.
