It can easily be crap. All depends on the construction and materials of that hinge. It looks a lot like it could be made of cheap plastic. Personally I'd like 2 arm one, specially if you are planning to use a heavier setup. Warranty will be effectively nil, with no spares readily available.
With Chi-com goods you get precisely what you pay for; good ones are not exactly cheap. You can take it from there I guess.
