High price but equitable manufactures in my view, since the keyboard is completely processed high dibasic. Very heavy but stable Keyboard. Stable positioning and great keystroke. The sound I like, even if you can hear the keyboard clearly. The ARX dock I find quite funny, and my cell phones can also be easily coupled (ASUS Padfone and Samsung NOTE2). Whether there is a lot more in the APP I can not say, but the idea I find very smart.
