A fantastic keyboard that, after a few months of use, has left its owner feeling quite content. I use it as an external keyboard for a macbook as well as a stationary PC at the same time (remotely to beat it), and occasionally I clutch to a phone with Android 10 or a smart TV, which is also an Android device. Connecting to different devices or switching between them does not result in any issues. Everything moves extremely quickly. I didn't test the range of action because I believe that working 10 meters away from a computer is either a form of shamanism or an act of total perversion. Except for the fact that you can get on to the computer from a remote location and input your passwords while you are lazily stretching out in bed. ;))) Genet used a full-size analog Logitech K780 for his research. It's conceivable for a wife to make more money so that, in the long run, she can save her nerves by not having to worry as much. That was something I needed to take care of for myself. However, I find that the keys on my K380 are easier on the fingers and more pleasurable to operate with than those on my other keyboards.
