I was seeking for a keyboard that had effortless, gentle keystrokes, and no cable tying. And she is this! It simultaneously connects to a laptop, a smartphone, and an Android TV box. Pressing the matching yellow key changes the device. It is ridiculous to claim that Claudia doesn't switch between languages. Either curvature is the issue, or the firmware created by the phone maker is flawed. In any case, the Google Play Store includes a Logitech program called "Keyboard Plus" that fixes this issue. I am satisfied overall. I must state up front that if you use it as a computer, there is no bluetooth adapter included in the kit; you must either have one built in or purchase one separately. Since firewood is loaded on Bluetooth when Windows is loading, you obviously can't access the BIOS with this keyboard, but some intelligent people don't want to comprehend this and see it as a drawback, which is foolish if we take this connection mode data account.
