Rating: 4/5 good to get it November 2, 2015 The Buffalo external WiFi disk works fine even if there are some issues with Macs as if it used for Windows and Macs you have to choose the proper formatting system, but it's just a detail. Fast and affordable works well also as a charging station for my iPhone, for the price I've paid it's worthwhile,

I would recommend this item to a friend!

Rating: 5/5 The Quick Set UP Guide does not provide complete information December 27, 2014 There is a manual http://manual.buffalo.jp/buf-doc/35020309-02_EN.pdf that can be very useful. After you plug in the device to charge the battery and see that the light turns green, notice if the light above the big on button is yellow. If it is, push the on button and hold it in for 3 seconds and the yellow little light will turn green and that means that the external battery charge port is off. Then you can proceed to install the Ministation-........ and password. There is also for IPad users an app available at the App Store that you can down load (Buffalo MiniStation2). The device works well and provides a wireless network to use. I have it connected wirelessly with my my Apple Extreme Router and I am sending the review via the device..
