"I don't think you're gonna earn too much money with it ... in general I think it's gonna earn maybe $15 a month"
And by "a month" they literally mean
a month; this one. Next month it'll be closer to $7, then $3, then $1 and pretty soon it's stuck.
Given that it sells for around $150 (there's a few cheaper out of group buys), the only reason to get this thing is if you're mining for fun, maybe want to play with the firmware some (though as largely a front-end to the static ASIC, not nearly as flexible as an admittedly much slower FPGA miner).
