A:Answer There is much misleading information here. If you want the MX mouse and MX keyboard on the same dongle; it wont work. The MX Keys uses the unify receiver, and the MX mouse uses the bolt receiver. They are not compatible with each other!!! Logitech sales an MX Keys gen2 (usually with the mouse as part of a business pack) which does use bolt. Note, Logitech also makes a MX Mechanical keyboard, which is Bolt, and you can use the same receiver. What a mess!!! So if your buying the MX keys and MX mouse separate, and hope to use one receiver, it does not work. you will need both receivers, or connect via native bluetooth.
