In addition, used on PC, remapping is really a pain: many resources to the wired keyboard, but little usable for it. The integrated Bluetooth connection on my dell works quite well, but is slow to develop (5 to 6 seconds while loading the bios, impossible to use for grub) in contrast to all other bluetooth keyboards I've tried .
I sent it, I buy the wired: I lose practical level and size, but at least I will have a keyboard worthy of the name. Pay so much for a keyboard less convenient than my laptop ... I give up.
