Anyone knows if this any good? Internet say this can make up to $15k a year using this.

Sure it's good, if you can afford the purchase cost and manage to ROI before difficulty gets too ridiculous. In other words it's a gamble.
Also expect it to have seen some use in the past(in true bitmain fashion).

At 5 cents for electricity, you can earn 25 thousand dollars, but this is only a possible profit, which depends on various factors, such as the price of the coin and the number of ASICs in mining.

A payback of 7 months looks very tempting.

Well. If you like next to lake you can build a small hydropower plant. Or couple 2 3phase huge motors 75Kw to have dynamo machine. You can get car alternators, take a most suitable engine belt and connect generators with the belt like so the rotational pull force would be reduced. Can work with one or two motor.

Or you can make lot of small Heron phountain. It's so water always flow by circulation.  I think you need a lot of this for that.

KS3 is the most profitable ASIC machine out there at the moment:

But of course, it depends on your electricity price, and for how much you can buy it.

To do this, you need to live on the banks of a river with a good flow and protect this equipment from thieves. If you have real examples of mining on such equipment, then I would like to see it. Such equipment requires the correct location on the river, and its installation would be illegal without registration.
