The keyboard does not live up to the price tag it comes with. Using Bluetooth with a personal computer is, to put it bluntly, a pain. The keyboard is always making an effort to "uplift," but awakening is in no way a quick process. The K380 goes through batteries much more quickly than my older K360 did when it was unified with 2.4. Although this does not happen very often and there is a good likelihood that clumsy Windows 10 is to blame for this, the keyboard will occasionally slide off firmly, and the only way to recover it is to restart the computer and reconnect it. Within the BIOS, there is no ability to enter anything or do any actions with this keyboard. The obstinate default configuration of F1-F12, and the fact that the only way to reassign them is by installing software from Logitech (which is also not of particularly high quality) into the system. The developers of the K360 decided not to provide a practical set of function keys, so instead they slandered anything. What has been going on with Logitech as of late is beyond my comprehension. The quality is slowly but surely deteriorating. Products are released that are, to put it bluntly, poorly designed and unfinished, and Logitech sets prices for them that are quite extravagant. Who was it that stopped the addition of Unifing 2.4 to this keyboard, which would have kept the F1-F12 setting in the ROM of the keyboard itself as opposed to the software in the system, replaced nonsensical fn with more common options, and filed a separate version for PC and MAC? Do Logitech, and we'd have the perfect portable clave, but as it turned out, neither fish nor meat was involved.
