I have 2 units that are sometimes working, sometimes not. S17 Pro and S17+. One has dead hashboard (exactly one loose heatsink) while all 5 other hashboards sometimes work. Where are you from and would you try to repair them or want to buy 'em out?
I'm in the northeast USA.
I'd consider buying them, but if they are partially working it may be better for you to limp along with them while profitability is as high as it is now. Guess that depends on how often the 5 sometimes working hashboards go down.
Let's say that two out of five hashboards work every 10th try if miner is preheated and other three hashboards work every 3rd try if miner is preheated. If they are not preheated, there is maybe like 5% that 2 of them will work rest will not work at all if atmosphere temperature is under 25C.
Sadly as RRZP028 noted, shipping from Serbia to China or USA is way too expensive for anything that is heavy.
I am from Serbia as well which means I might be in need of your recently acquired skills RRZP028.
