Went China and visited headquarters of Dayun to buy miner in person picked up a Zig Z1+. (wasn't sure if I could trust site), When I got back to USA I ordered the http://www.dayunmining.com/product/zig-d2/ 

overall it seems to be alot more reliable than the zig Z1+ has been running steadily since I turned it on. Only complaint is that the fan speed is really high when getting advertised hashrate, if I set it to 80% the noise and heat is greatly reduced.

Profit has been ranging from $200-$780 per day, depending on which pools it switches to.

Overall a good miner
