    Great feeling keyboard

    This keyboard has a great feel and look. My only complaint is that sometimes I have difficulty connecting but even considering that, it is my new favorite keyboard.

    Backlit Bluetooth Keyboard -

    Loving this … as it has ‘cleared’ my desk with ONE keyboard that I can use with my two computers and iPad … and easily switches between them.

    SM3 Slim Mechanical Backlit Bluetooth Keyboard

    Received in excellent shape with carefully designed packaging. The keyboard itself is well designed. I like most the mechanical keyboard setup with full size layout and esxpecially the lighting. It may take a little to get used to the spacing of the keys since I've been using an apple keyboard for years. The rechargable power source is new to me and I keep it plugged into power all the time. EXCELLENT PRODUCT!!
