I came to the same conclusion as you! Best combo of geometry / boost / price I could find.
Mine arrived yesterday and I'll post more once the build is done. The Airwolf store on Aliexpress was very responsive and sent pics before shipping. In total it took 6 weeks from ordering to delivery. I think painting delayed it quite a bit.
I'd hesitate to recommend it yet because I haven't built it, but experience has been great so far and finish seems excellent. I don't have the issues mentioned in the post above: dropouts are fine and aligned, and my fork (2018 Sid RL) clears the downtube on my size large frame. The 2.4 inch max tire clearance seems conservative. I've test fitted a 2.35 Barzo on a 30mm rim and there is quite a bit of room.
Hope this helps!
