A tad more expensive than last time its seen on Amazon AU https://www.ozbargain.com.au/node/729511
Since I've got this to replace my MX Master 2, I really like the mouse for long hours on the pc, and at this price I think its worth it.
Caveat
1. This uses Bolt unifying dongle so its not shareable with other devices (notably MX Masters)
2. There's no free scrolling (albeit there being a smooth-ish clicking scrolling)
I also believe it’s noticeably smaller than than the MX vertical.
