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 advise proceeding with caution if you're considering investing in these miners.
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!
Yes Innosilicon is a POS! They charge very high prices then flood the market so that no one will make their money back. I bought 1 from Halong and 1 from Innosilicon and Halong was doing it the right way by selling 1 batch every 1.5 months apart but they sold their tech to several manufacturers that just want to screw everyone. I will never support these companies again and I will just stick with Bitmain. At least they don't drive the ROI up to 2 years, put outrageous prices on miners and they have better support/warranty.
