This seems like an already awesome price for this newly released mouse, the cheapest I could find in Aus other than this is about $125 Delivered. Price match at JB Hifi if it's closer to you.
For this price it's definitely worth taking it over the original one :)
Features:

The mouse has a wireless range of up to 10m, letting you optimally position your devices within a spacious area.
For added convenience, the Logitech MX Master 2S can be recharged in just 3 minutes to provide a day’s worth of power. When fully charged, its battery life can reach up to 70 days^.
The wireless mouse can connect to your device via either the included Logitech Unifying Receiver or through Bluetooth low energy technology to suit your needs.
Enjoy :)
Apparently, an issue with the previous model was that mouse acceleration would always on and you'd have to fiddle with third party software or tinker in the software itself to turn it off.
