Visually, I really enjoyed the size. Its advantage is that it is small and light. One can easily carry it from one room to another, see put in the pocket.
It is easy to install on furniture as it is not bulky. By far one might even take him for a remote control.
I have noticed that it was solid. In fact one of my children has dropped to the ground and he was neither damaged nor broken.
To use the keyboard simply plug the USB adapter and then turn on the keyboard and it works alone. It's easy and fast :)
Personally I used it on my pc Windows and it allowed me to control everything remotely. Via the touchpad, you can simulate the mouse. The reaction time is really excellent.
On a type of media player Western Digital Keyboard also works (in qwerty) without any manipulation to perform.
At the battery, this one takes a long time even though I did not quantify the exact time. And to recharge the keyboard simply connect via USB.
In conclusion, I am amazed at the quality of this keyboard and especially that quickly becomes indispensable.
