Hey,
Next time before you buy something better think twice before jumping into china miners
What about the original software is it working?
I was playing with grind seed units just once grind seed chip
I can tell you that I was mining happily for hours and cgminer fork of greendsed was showing me hashes flowing when USB was not working at all
These guys are funny
So chose what you buy wisely for the feature
Never buy something with close source that is all
The original software works, and works great after I fixed it (their web gui was all screwed up pointing to the wrong files and such. Fixed the pointers, translated it all to english, and it's been mining 24x7 since I did that.). I get a steady 1.2Th/s from it. However I was contemplating putting it on leaserigs and all works except for the ability to change pools via API.
And for what it's worth, *I* didn't buy it but did agree to it. And as far as I know, most of the hardware is "made in china".
