Why Tom Thumb, because it can be used effectively with thumbs a bit like this generation smartphones dedicated to Chat. But it is also why it is designed as it is primarily intended for use with SMART TV or SMART BOX and it works really well. There's even a microphone (Skype) and a backlight that can be cut to save battery. The more this keyboard is the addition of a touchpad, so you do not need a mouse that does not necessarily work well in a couch and saves a USB jack on the TV. The touchpad responds perfectly. Just type a finger to the left and two fingers to right-click click. Slide two fingers corresponds to the scroll function. But there is also "mouse click" buttons on the keypad. It's amazing the number of preset keys that are found there. True, it takes a little getting used to but it's small keys much more convenient than the remote supplied with SMART box. Moreover, it is very soft and pleasant to the touch and has a very good finish. It can also be used with a tablet or smartphone provided you have an OTG adapter in which you can insert the USB Dongle. And of course it works perfectly under Windows without external driver. Note: To conserve small battery, the keyboard turns off after 3 minutes of no activity, just press a button to turn it back but not on the touchpad! To recharge any suitable wall charger. The Mini USB cable is included One regret the manual supplied is in English. Why I have provided maximum above explanations.
