Not to be a big skeptic, but can we see actual mining rewards / performance somewhere?
I get that you say the ROI is 70-200 but I dont see much evidence that its anywhere near that without some serious video/photos its hard to put trust in something without ensuring that it does what you say it does.


What I see is:
1) GPU mining is losing its profitable and ASICs are knocking down the doors, this causes people to find other outlets
2) The OP is probably getting a referral payment for any hardware sales with these two companies (if not, maybe he should? I dont know, being transparent about this would be best)
3) OP has the ability (or could?) to lock the device with a signature to only work with his software, which makes them paperweights if he chooses to do some shady things (not saying he will or thats the case)


I would prefer decentralization in this field, the only way that'll happen is to remove the barrier from entry between the manu and software, middle man are reaping the rewards here.
