The claim of 2 coins per day checks out with this calculator:
http://www.alloscomp.com/bitcoin/calculatorThe question is, how much electricity is it going to use (probably small) and when will it arrive. If it's going to pull a BFL and arrive a few months later, you've already lost.
looks like if i had the box right now it shows this, using a 2.5th/s not sure what everyone is talking about the electricity used at my house though, how much have your electric bills jumped?

My friend, before you start, I would recommend you to fully understand the difficulty process, that increases the mining difficulty every "x" days
To help you, I recommend this calculator:
http://bitcoinwisdom.com/bitcoin/calculatorOn the start date, write the numbers of days ahead you will start. For example:
Today is Dec, 3rd. If you will start on Feb, 3rd, write 60 (sixty days from now)
The first box is the difficulty increase (it is already set to 30%, it maybe be more or less indeed, but it's a good measure)
You can set the hash rate and the amount you expect to spend. Attention because it is in Ghs. 5Th is 5000 Ghs.
Run many simulations before you buy, add more days then the factory promisses to deliver (because one or two weeks can change totally the scenery)
I am also thinking to buy from xtreme miners, but I am afraid they might not be able to deliver it on time, or worst, to be a scam.
I am not saying they are, but they are starting a new business and as nobody had heard of them before, doubts arise. Many promisses but not many information about the company and creators.
I might buy it. I will wait some more days to think.
Hope I could you help you.
Best,
