Thats rubbish pricing: as purchase price per 1 ghs it is 0.0016 BTC you can buy for half of this price with this level of fees..
Getting to fees it is nice to annpunce 0.00184 per ghs but if one looks closer it is dare expensive:
0.001184 per 1 gs makes 1.184 USD per ths
so 1 unit cost is 1.155 x 1.184 = 1.37 USD a day burning 12.26 kW
so one pays 0.112 USD per kW and that is expensive....
fees for this unit should not be higher than for other units
thats the sticking point not mentioning high purchase price which makes Bitmain making bucks....
why not set them up on some more realistic per kW rate as 0.096 USD?
