Have a Pc "classic" is becoming less and less indispensable except that sometimes typing on a keypad can be unpleasant when entering text a little longer than usual. This small qwerty keyboard is very convenient and offers a solution for the seizure. Installation is easy and immediate. Just turn on the keyboard to connect to the smartphone automatically. Of course the keyboard is a reduced dimension. It can slip into a handbag. No need to be recharged constantly, the battery takes longer. The keyboard has just the width of two hands the keys are not too small so far. I use it on a smartphone xperia on an iPad Air or even on my pc (tv connected to the screen that makes typing a remote text). I tested with several smartphones and have not found incompatible. If using Android system may have to change the settings of the keyboard in the smarphone to put the country France by default. It took me to do it because the keyboard was in QWERTY. It is a pity that the manual does not indicate a check Android settings. Otherwise the keyboard is nice. The small desk to ask the smartphone is convenient. A mobile and useful tool especially if we are not addicted at all pc
