I got the miner from bitcoinware and hasn't work since day one. I noticed one of the screws holding the heat sink didn't have a spring behind it.
I've had issues with Bitcoinware, check my feedback sent if you want. Anyways, after 1 month of bad communication on their part, the issue was resolved, but you really got to hold your end of the stick.
You can try fixing it but when its DOA...
The problem is for returns they wanted me to do it at my costs, so. Lost of mining time, extra expenditure AND their miners are overpriced as f**k. So yeah. Return, cut your losses and get your stuff somewhere else.
