Minersource, one of the biggest of all resellers screwed plenty of people. There were multiple problems with multiple other resellers of Bitmain equipment and problems with the transfer of warranties. There is significant additional risk placed on the end customer for very little benefit. And the fact that your signature advertises 3 companies, two of which don't exist and 1 which doesn't like resellers really doesn't add weight to your argument.
They were horrible to deal with. They decided to steal pictures of my SF100 review. They used it on their site for a profit or gain.... which they never asked permission for.
I actually met the top "brass" i guess at a booth at a convention(while back). I talked to them saying I wanted it pulled and asked how it even got up there.. it was very very hard they said they did not know how it got up there. After I pushed they admitted they might get photo's off this forum....
They gave me a card and said they would give me a deal or pull it (don't remember exact it's been a long time).... sounded fair. They never gave me anything and did not take down photo till they stopped selling item.. Needless to say I don't trust all re-sellers this is part of reason I link direct to companies. There are some good re-sellers but some are not good at all.
