A:AnswerHello the MX900 as a combo will require the USB dongle to be plugged in and connected to your device. It is possible to pair the combo to a secondary USB dongle which will not interfere with the first USB dongle, if they are out of range of each other at more than 33ft.
A:AnswerHi TeddyP the MX900 has the K800 keyboard and the MX Master 2s. The K800 keyboard does not support multi device or flow. The MX Master 2s does support multi device and will work with Logitech's Flow.
A:AnswerMine came with what I believe to be is the MX MASTER 2S - I have had mine a few months now and have been very pleased with the performance of both the keyboard and the mouse.

A:AnswerHi LPR, you can buy another cable if you would like too, but the mouse and keyboards have amazing battery lives. So you shouldn't have to worry about charging them up very often if you turn them off when you're not using them. Hope that helps! -N from Logitech
