The only low-cost external wireless keyboard with backlighting that is compatible with numerous devices. And this is in late 2022, when Apple finally packaged a decent keyboard (!). It's a wonderful product, no doubt, but not worth $130 (and probably not even $80). I though maybe someone might find it helpful to know that the key travel experiences are on par with the much cheaper K380, which "can" carry three bluetooth devices. The tactile feedback is very identical, with the exception that the "clay" keys are a touch more forgiving. The K380 is an excellent device for the price (three and a half times cheaper than this one! ), with key travel and typing feel that are on par with those of the Apple Magic Keyboard. Naturally, comparing the subject to the K380 in terms of utility is pointless; here, the adapter is the most practical addition, along with the digital block, additional buttons, and settings. The button layout is user-friendly (with the exception of the left shift). When compared to other keyboard layouts, this one is actually fairly sensible. I was able to plug it in and start using it right away without any problems; all the buttons perform as expected in both MacOS Big Sur and Windows 10. But, you know, $130 is much too much for anything like this. Neither the materials nor the improvements seem worth the price tag. Simply no other options available.
