The product is light, pleasant to the touch. The pad is multi and allows, on compatible applications, zoom in / dézommer with two fingers.
Having mobile use of this product (in my backpack or in the trunk of the car), I enjoyed the switch on the side (which turns off the keyboard so completely to save battery) and trapping to store the USB receiver (and therefore do not lose it).
For those who would use on an Android device, you need to download the free "physical QWERTY keyboard" Google Play for Android-based, physical keyboards are detected as QWERTY keyboards, and some devices not possible to change this configuration.
I have not yet used on a computer but I assume that it must be just as convenient.
In situations of low light can sometimes regret that it is not backlit but this option is not the same price range!
