I DO RECOMMEND  this miner , cause I was using cast-xmr and it was showing better hashrate , but my average on the pool  was low 17500-18000.
  Then i started using your miner and it is showing less hashrate may be 5% , BUT my average hashrate started growing and now after 24 hours it is 19955 and is stable . Keep the good work boys!!!!!!!!!!!!! And guys don`t get fooled by the better hash of other miners it is not real obviosly!!!
