It's saddening what 1 year can change in the mining business, just picking a random number of 6 cents per KhW, a year ago the same miner made 5.5$ a day, today it hardly makes 1$ a day.
I remember when this gear first hit the market, people paid almost a whole BTC to get it, I am willing to bet that 90% of them have yet to see ROI, in fact, I highly doubt that many of those gears are still online anyway, probably most of them are dead.
This is a great example of why you should not go to an online mining calculator and make business plans accordingly as if the numbers are going to be the same forever, we will be saying the same thing a year later for gears selling today where ROI seems like 1.5 years, it's pretty crazy.
