Seems so, i have asked this same question of a number of sellers/resellers and manufacturers.
the consensus seems to be - buy buy buy, dont think, just buy.
coupled with - everyone else is a scam, we are ligit (misspelled on purpose)
dont worry about making your money back, this. is. bitcoin. m00n, etc
from what i can work out, they only want retarded rich and or stupid buyers but they wont come out with it - just keep dangling turds painted to look like carrots from a distance - BUYNOW!!
I think I never pushed any marketing ... sentences like get rich with mining or ... that the products I sell are doing ROI in a month or a year or whatever ... each buyer has to do his calculations on his own ...
There are ways to do ROI ... faster ... then others ... I for my self moved over from SHA256 mining to scrypt earlier this year because I estimated the market in the SHA256 mining world getting to heavy ...
.... there was never a manufactuerer which sold his gold monkeys to the public instead of mining with them himself ... every mining product that gets on the market ... has been valuated ... to be at the edge of beeing worth to mine .... there where some exception ... but they where all corelated with an unexpected price increase of the bitcoin ... in favor of the buyer
