I paid for 3.2 btc for ~10GHashes, expecting it will break even, at least in a year. may be some more for second year as profit.

Everything is ok so far, and received my 0.1 BTC as my weekly payout.

Except September delivery announced, received in late in October.

If this extends for 32 more weeks (8 months), then it will break even with my investment, which is great.

But I think it will never return my investment.

We have finally got our hands on a Butterfly Labs ASIC miner.  As most of you know, production release dates have been a enormous problem for BFL.  The miner we are testing was ordered in March 2013, it was received October 31st 2013. As you can imagine, the wait time essentially nullified any chance of making a quick return on investment.  With ASICs flooding the market, the mining difficulty is pacing with the production numbers.  Want to make a good return on your mining investment?  Get "fast hashing" hardware quickly. 

Unboxing the unit was also an ear opening experience, as I could hear screws rattling & sliding around inside the case.  Loose metal objects floating around powered electronics can be an expensive mistake.  Fearing it may fry the electronic inside, I removed the offending screws, and proceeded to put the unit back together.  I then remembered that BFL had to change their original design of the Single & Little Single ASIC units.  They had to double the case size, to accommodate the 30 & 60GH/s boards.  The resulting internal case design & assembly appeared to be rushed into production.

You going to heat your house with GPU? You better think twice cause I see some forum member saying there is weird smell while GPU mining. It might have serious side effect.....
