I have purchased many miners from Bitmain, S1 and S2. Never has one appeared to have seen any use. In fact, they were so clean and unscarred I wondered if they had even been functionally tested. But I have yet to have ever had a DOA or failure of any kind.
Indeed, same experience. But perhaps the last miners that they sold for 0,4xx BTC where used in BITMAIN's farm... Thanks to the people who posted their opinion is this thread. Appreciated even if you disagree.
Looked exactly like this, maybe a little worse (picture from another user with the same experience as me).
Didnt take my own pictures, i had other things going on and its not like i had recourse.
