So glad I had all my mining power there.
Rockminer RK-Box 480GH/s same day shipping 399$ here

They have 10% horrible reject rate, making them running at 440Gh/s like a S3
They do the job but less efficient in power and reject rate.

The main reason why i like antminer s3 is because of a few things i can get it at supplier price, easier to get in my place compare to rockminer, in my country is easier to sell off the antminer(people just like the brand) and the power consumption is very low.
