Their contracts have a stipulation that you can't disparage them in any way, and that disputes will be mediated by a court in hong kong. Keep both of those in mind as well. That makes it hard to trust anyone who currently has a contract with them's comments on the matter, since the chinese are notorious for controlling speech and strong arming people.
Edit: be sure to read all the fine print thoroughly. Especually penalties. They could, hypothetically, take money back if you failed to meet some deadline etc. This is speculation on my part, but you should always read every single line and fully understand it before you sign legally binding contracts. Especially where money changes hands.
