Thanks for the update! And I suppose that you guys have made some little background work about the LK Group Ltd. before you sent that 108 BTC to them, right? At least their website raises more questions than answers about the company itself... 
Edit: there seems to be an another company too in China with exactly the same name but doing slightly bigger machines: http://www.lktechnology.com/?page=product

Looks legit, these are aka dragon miners
see this thread : https://bitcointalk.org/index.php?topic=523634.0
What did you expect for reinvestments ?
That's great, I hope Cryptx buys more miners from China in the future. The Occident is not well adapted for mass-production of electronics.
