The flat keys, a spill-resistant keyboard and a comfortable width in order to affix your ten fingers (or more if you are an alien), qwerty keyboard that offers opportunities for use in accordance with expectations of mobile users. Note that this keyboard is of exclusive use to connect to Apple devices. If some reviews say that indeed it is recognized by android devices, it should be noted that not only the keyboard shortcuts do not match but it will be the same for some letters (I could measure it with my Nexus tablet) . So I advise you not to risk to this purchase if you are owner of an android device. By-cons, brand apple users, this keyboard will be many occasions useful.
Appraisal: a comfortable, full keyboard, Bluetooth, and ergonomically splash for portable use Apple brand oriented.
