It took a long time, but I was finally able to integrate many devices with the help of a single keyboard and an MX Anywhere 2 mouse (yes, the mouse can also function with three devices through Bluetooth). I had longed for a portable keyboard that is compatible with any electronic device without having to do elaborate dance moves with a tambourine. I have a computer, a tablet, and a phone. The main computer is working, the tablet is an auxiliary for personal mail, and the phone is for conversations, vatsapiks, and other SMS ok. It turns out that it works as well with any device as it does with a full-fledged PC, with the only difference being the size of the screen. The lack of a Bluetooth adapter is not in the least bit problematic because even televisions, much alone current computers and other electronic devices, already come equipped with Bluetooth. Someone is unhappy about the necessity of an adapter, which indicates that it is time to get a new personal computer due to the fact that the current one is both physically and morally obsolete. It's possible that the fact that the Bluetooth capability is built into the motherboard, rather than being provided by a USB dongle, is the reason why I've never had any issues while using this keyboard to access the BIOS. Buy with confidence if you desire a PC peripheral that is both tiny and convenient, and if your modern technology supports both wireless and Bluetooth connections. In some instances, you might run across some problems.
