I for one am going to stay away from those Dragon Mint miners for now. I've seen people talking them up but it still scares me. The fact that even one person is coming forward saying Halong Mining is misrepresenting them is reason enough for me to stay away (If you do your homework there several other reasons too).
There are safe/sure alternatives.
Oh and you have to spend $8550 USD + shipping and wait for months just to see if you are getting scammed. I have a day job and can't gamble but I am hoping they are legit. If its a scam its pretty elaborate.
Edit: The $8550 number is with their power supply.
