Hi, thank you for your reply,
I am happy to answer your questions. We currently have two engineers trained by bitmain's repair shop. Because we have mining and hosting service, for sensitivity of this industry and safety purpose, we will keep our address for our clients only. Our phone service will be online next week. S9 is the most popular mining machine, and for supply chain reason, We only repair S9 for now. Unfortunately, i have no pictures can provide.
We already fixed repair ticket error, thank you for the report. All the machine price and notes are the same as bitmain because we are selling bitmain's stuff
