I bought the one with USB dongle, very easy set up on Raspberry Pi 3. Just plug and play! When the backlight is enable if not use the light goes off or maintains a dimmer bright until you click anything. It is true that when you are on a dark room is difficult to enable the backlight unless you already know the buttons by memory. Overall a good product, cheap, very light and thin.
