I ordered 42 antminers S3. But 4 are not properly (1 half speed, the rest even worse). Offcourse I submitted a 'ticket' to webmaster@bitm... with all order numbers etc., a few days ago, but not an answer..? In the pre-sale fase they answered within 3 hours, but when seeking support they are 'busy'. Does anyone else encounter this problem? If yes. The pre-order scam is over and we got a new scam starting here..
