I mean, the Thorfire TK15 was actually much less expensive even with a coupon from Banggood.
If I wanted, I could easily buy 2 torches, mod them with SST-20s, and then sell them to friends.
IMO, the advantage of Aliexpress/Banggood is not really cost. It’s actually living on the edge of tech.
I mean, you could only get the Q8 from Banggood for a looong while.
