the thing that's worry me about the unbranded frames is how do you know the frame will withstand the rigors of riding - where's their R&D and quality control.?
carbon aren't going to bend before it catastrophically fails and you won't have time to react at 60+ ks on a descent.
now there's lots of forums where riders report no problems and of course there's branded frames that fail as well, do some googling on the factory conditions, the lack of quality control and I don't know mate, is it worth saving a few bucks on something that you'll never know if it is truly good enough to handle rides over the years. Where's the comeback if it fails? Where's the company backing to ensure their product can withstand what we put bikes through?
fake specialized frame = face plant.
