All of the US based ads look way to shady for me. Thats why I want to send it to a bitmain repair center in the US.
Zeusbtc is a well-known site here on the forum where you can able to buy parts of any ASIC machine and partner with trusted repair companies.
They have a list of US-based repair shops look at this link
https://www.zeusbtc.com/RepairCenter/USA/This is on the site, "Note that the repair site information provided by Zeus Mining free of charge is based on the photos of the repair site, more detailed information needs to be verified by yourself, Zeus Mining does not assume other responsibilities." If some people have used any of these listed vendors please post, but from looking at the US based repair centers its a email or phone number. Only Alpha Asic Repair has a website.. The pictures zeus is talking about on their site tell me nothing and how could you verify them as legit. I have spoken with Alpha before and they seemed a little over anxious to get my machines. Found them originally though a post on here late last year by a new user with no merit. I may have a new user account but I have lurked here for a long time, way back to the release of LTC gpu miner. I've seen so many scams come and go, just don't want to risk my asics with randoms with "pictures" as proof they repair asics.
