I did. Many hours researches on it. I even sent email to them twice re a OEM opportunity for a China's medical device company, but never receive any reply. A bit rude, there are many other companies I can choose actually. I don't wanna ring them now. Forget it. But if anyone knows the management, just ask them why do not reply to me, if not suitable, at least say Sth.

What I mean is its business should be very profitable, but no,just little. 3% profit means nothing for such a company, it needs changes.
