I don't know why op mentions ROI when you can't get ROI on them..
Ok, I'm missing something. I see lots of people talking about "never" making ROI on miners varying from these little toys up to 400 GH/s ASIC array devices. What timeframe are you people looking at? The ONLY reason I didn't preorder a KNC mining device is I was unable to raise the cash in time. Extrapolated over a year, difficulty would have to rise to close to a billion for me NOT to make a positive ROI. Not saying that necessarily applies to the USB block eruptor, which seems to me more of a novelty item, but still!
You want a good ROI in bitcoin? Start promoting it to folks who might use it as currency. The transactional end of things is sorely neglected at this juncture. In the long term, mining for bitcoins WILL CEASE. Then the only profits to be had from the network are transaction fees, and the coin itself rising in value against other currencies. THESE are the issues we should be focusing on, as if they are not addressed, Bitcoin will end when the last coin is mined.
If you're looking to make ROI in a day or two, you are better off going to vegas, where the odds are against you but the possibility exists. If you are interested in promoting the idea and ideology of Bitcoin, then a year or more to realize ROI is not egregious.
Good for you.
But for me IF you are in mining, the ROI is a part of the math.
Of course if you are just a hobbyst, an artist or a Blockchain protector (sic)...that's another story.
The problem here, is this device are overpriced.Clearly.No ROI.NEVER.Only for Friedcat.
When you say "Then the only profits to be had from the network are transaction fees"
Are you really thinking you will be still around in 2140 (source

Seems you can wait a little...
Learn about things before promoting them.
You missed my point. Or perhaps I wasn't explicit enough. I did kind of get sidetracked in that I feel quite strongly that too much emphasis is placed on mining and not enough on developing general acceptance of bitcoin as a viable transactional instrument.
What I am failing to understand is WHAT TIME FRAME are you (and the many others who are complaining) are you expecting to break even? I run calculations based on both optimistic and pessimistic numbers rather often, and it still seems that the bigger devices will break even in a few months on the worst end of the scale. That's pretty damn good. Better by orders of magnitude than you would expect from successful gold mining. What, if anything, am I missing? Or is this all just a quick scheme to get a quick buck to a lot of people? I tend to look at investments in the middle to long term, rather than tomorrow.
Oh, FWIW, I intend to live forever
EDIT: I failed to cover your other point. I agree fully that ASICMiner devices are vastly overpriced. They are not going to be the only game in town much longer, however. I view this particular device as a toy. I probably will buy one, if the price drops a bit more, just for the sake of the history of it. I wouldn't expect it to break even, but it's cool looking. The problem I'm seeing is people are saying the same thing about devices that very well should break even in a very reasonable amount of time even if difficulty increases by an order of magnitude or more.
