Their contact address is Duanhuitrading@hotmail.com, and the company name is Duanhi Trading Limited company. I found a complaint filed against Duan Hui Trade at Alibaba Link hidden: Login to view and it's not far that they refer to one company.
I can see brand name electronics being offered in their website, and unfortunately China is not the right place to source these kind of items.
Let us know if you need a list of suppliers. :)
