Very good keyboard, much better than what I expected. Responsive enough, no latency, good touch feeling ... The only complaint I have at the moment is that there is no light indication for upper case, but it is the case of many keyboards of this size. So I said that this is a compact keyboard (it has roughly the width of a laptop keyboard 15 "), but it exactly meets my expectations. I tested it with my iphone / ipad and it works well. It remains to discover its autonomy with time ... Overall I would recommend the product and the seller.
