Your joking right? You ever heard of opportunity cost? I could have put that money to far better uses than an
Interest free loan for sp-tech. I could deal with the lower hash rate and higer power use but this late
Shipping was just the icing on the cake
I am not joking, but first you complain about not getting a ROI and when I presented you the option to get your ROI you complain about different things. I don't like the late shipping either, but you have 2 options available(refund, compensation+delivery) and you don't like any of them except for the one that is not possible (6Th/s and delivery 2 weeks ago).
That's the single most important issue in this situation.
Just as a closing point, why not show us all how clever you really are by demonstrating how an AM chip based system will make any ROI, comparing it to an SP30? I'd love to see it, I'll bet a lot of other would too and you've obviously got lots of time on you hands. If it's too difficult for you I'd be very pleased to help.
I admit that I think that the most important issue is the situation, but I will not go into details because of my "SP-Tech shill" status. I am glad that I am not the only one to see this.
As for the AM miners ROI don't forget to add 1 extra days for the countless screws that you have to mount.
