I`m in the same boats as alot of you. DOA board on one of my S7, they`ve received my board 3 weeks ago, and i still don`'t have shipping label for it. they tell me they found the board and did the repair on it, 2 weeks later i contact them and they tell me, no repairs are not done yet, it takes a few days. It`s BEEN 3 WEEKS for F... sake. and now i got another blade that died, it`s still under warranty but that one is going to Denver. even if if i got to pay for it.
i will NEVER NEVER buy from bitmain again. i bought 5 S7 and so far,
1 x DOA full S7. 150$ to send back and 1 month to get it back
1 x DOA board, 75$ and still in limbo
1 x board died, this one going to denver
not a very good tracking records and very poor RMA service. and all the ignores from them and run around.
i`m also going to post this in their thread in the hopes they will read it and other people will think twice about buying from them
