So a few questions about hashnest

First and foremost, when the maintenance for a specific type of miner exceeds it's revenue it stops mining and you can redeem your gh/s for the actual hardware but you have to pay shipping. I've heard the shipping charges are pretty unreasonable, but what are the actual shipping costs?

Second, could somebody provide a better explanation of the Pacmic contracts because from what I've read it seems like the pacmic contract is
You buy 1 TH/s of a specific type of miner.
It mines for you and pays you back what it earns with each block mined until the principle is returned.
In addition to that you receive interest equal to (Unpaid Principle)(0.45)(1 Satoshi) every second.
If the miner is unprofitable for 2 weeks then it stops mining and you're out of luck.
You also don't have to pay any maintenance fees on the miner.

I have only read negative reviews about the Pacmic contracts though so I don't understand if I'm right because it sounds like a pretty good investment from what hashnest says.

That is all

I am asking for 0.001 BTC for my first rep loan. I will repay 0.005 as soon as I see the transaction and it's also confirmed. The balance on the address is 0.0041 because I made it specifically for repaying this loan.
