I don't understand the logic in these knockoffs.
1TH in ANTMINERS @ $750/miner (x5) is $3750.
Those are being delivered today.
So this new 1TH box is $5K and thus $1250 more to save some power and wait longer?
These should be $3.5K today and decrease 20% in cost every two weeks to compete.
I made the mistake of buying a 220GH Avalon Clone with dual 650W supplies that:
A) Took weeks to ship (despite "in stock" claims) when BITMAIN was an actual deliver-in-3-days.
B) Had crap quality control and was a poor design that resulted in a large failure rate of units. (blow out the PSU every 30 days behavior)
So based on that experience sorry but I am just very skeptical of these knockoff 1TH boxes (especially when they use the same dual-supply design but don't properly isolate each supply from the other). I can't personally tell which of them are rock solid as advertised and which ones are rejects that already were ran semi-stable for a month but fried some parts and they got it working again by getting it reflowed and replaced enough parts to make it stable "enough" again at a lower clockrate to sell it off to the next sucker...
No way I am risking BTC on this.
Now if you take PAYPAL we can talk...
