More than just a keyboard, this device can also replace a hardware KVM with the use of a Logi Bolt receiver. I was contemplating buying a different keyboard, but when I found out that I could use this and a MX Master 4 mouse on the same Logi Bolt Receiver, my need for a KVM disappeared. I truly enjoy the ease in which this keyboard connects to the Bolt Receiver, and how easy it is to go between computers. This capability really needs to be highlighted more IMHO. I have also been using this keyboard for more than a month on a single charge, and the battery indicator states the keyboard is at 85% now. Keep in mind that I do not have backlighting set to stay on; lighting illuminates when my hands are near the keyboard, and turn off after I'm finished typing.
