It's a nice keyboard for the price. When you hold it in your hands, this becomes immediately apparent. has certain advantages: The keyboard supports a maximum of three simultaneous connections. Weight. The keyboard doesn't creep over the desk or my knee, so I'd say it's well-balanced. The overall level of quality is 5+. The connection remains constant and the signal does not fade. Contains drawbacks: Compatible with both Windows and the iPhone. Especially for iPhone users, the interface takes some getting used to. The location of the question mark (?) on iOS is currently unknown. While this isn't necessarily a drawback, I don't find the round keys to be very ergonomic.
