A keyboard the size of a remote control, it does not necessarily provide the same as a traditional comfort. Yes, but a keyboard that fits in a shirt pocket, it's good for a Raspberry size of a credit card ... We must not look to have a perfect mapping and use function keys, but when this is just to take the set for mobile use, relief, then yes, it is fine. Cons: the location of M next to P (though we made it surprisingly quickly), F9 through F12 function keys, and a fairly limited scope (it works well, it does not work, it jumps letters when typing ...) and it is frankly annoying (or so we must keep the key near the dongle). Strengths: the right SHIFT really useful, mouse click keys left of the keyboard (which had appeared to me as a weakness before buying) the handling of the keyboard is much easier. At both hands, index finger right on the screen to move the net and left index finger to click, without placing the keyboard on a knee or a table. Practice on the sofa, and significantly better than the Rii mini, flagship model, which i had in hand an evening.
