CAUTION!!! Unless you are HODLing coins for future profit which may or may not happen or enjoy a really expensive hobby with quickly diminishing rewards. I'd HIGHLY advise proceeding with caution if you're considering investing in these miners, or any miners for that matter.

I bought a D9 on the first wave from Innosilicon and was a strong supporter. Unfortunately, Inno flooded the market - driving rewards to down so quickly, even with the 1 one get 1 free promotion achieving ROI or turning a profit is so far down the road. And it's only going to get worse with the superior iBelink miner available now at similar pricing and Obelisk DCR miner becoming available soon.

Thank you, Inno!
