It's an enthusiast device, quality built. Not something you're gonna make ROI on
I usually describe it as a hobby device. You don't make money restoring old cars, you don't make money riding motorcycles, you don't make money brewing your own beer, and so on.
There are ways to make money mining bitcoin, using a device like this is not it. But it is enjoyable to tinker with.
And, still did not get my tracking #.

I buy it because I purchased everything he ever sold.
And i hit a block of ltc+doge with his ltc miner.
Held the doge and sold at 17 cents a coin.
I made about 2k on that mIner
He the builder helped with l3 miners that saved me about 2.5 kwatts an hour for a year.
