I bought a miner in June from them but they never send it. They promised to refund but I never got my money back. <br/><br/>I lost a great opportunity and a lot of money. <br/><br/>I cannot understand all the good comments, as they do not send or refund. Answers to mails are very slow. And telegramm messages were not answered or took days for a reply. <br/><br/>!!! Be very careful with them or go to some better place !!!
