The difference between the two mice is that the mouse with item number 16739167 is Bolt USB receiver and Bluetooth connection technology and the other mouse is Unifying USB receiver and Bluetooth.

The regular (1st gen) MX Keys only works with the Unifying receiver. The Bolt receiver is only compatible with the MX Keys for Business or MX Keys S (2nd gen).

Can be operated with both dongle and Bluetooth. The choice is yours.

MX Anywhere 3 for Business: Only works with the new Logi Bolt USB dongle. This is included in the scope of delivery. MX Anywhere 3: Only works with the Unifiyng USB dongle. This is included in the scope of delivery. If you are a Linux user, the Logi Bolt is not yet recognised by Solaar. So you have to configure the mouse via a Windows machine and the Logitech software.

Yes, you can still tilt the scroll wheel. Not any more with Anywhere 3.
