The idea with solar is good, this was the real reason to buy together with the numeric keypad.
But the more I type here, it becomes clear that it is not nearly is good quality - cheap plastic!
no comparison to the org. Apple, the label is stuck - no idea how long it keeps. On the product image it looks different.
100% compatible, well, if I unpack and connect to the Funktionstastem function and is not the case, screen brightness is not adjustable, as well as the other functions do not match the current Mac.
I'll send them back and prefer to stay in the "small" aluminum keyboard. Perhaps if more Bluetooth to Bort would be, but it is also a USB port occupied.
Too bad ...
