I saw that deal and purchased one a couple days ago. One day shipping means I'm about 24 hours into using it. Running Merlin 384.13.
I took my older AC68U and set up AI Mesh, with Ethernet backhaul. So far so good.
HW Stats: Rev 1.5
MFG: China, Year:2019
From what I've read I'm glad I got a 2019 version, since there's anecdotal evidence that 2018 built models tend to have a slightly higher failure rate of the 2.4GHz radio.
I have already experienced the failed to reboot twice - where you have to power it off with the button for it to come back on. It does surprise me Asus has not bumped the Rev and fixed it.
