It looks almost identical to my one, which costed twice form an Italian "maker" (probably they simply apply their logo on the very same Chinese wing)...
while it it possible that the wing is manufactured by the same folks that make your brand name wing there is no guarantee of that. A good company will have a quality assurance/inspection program with an outsourced manufacturer that ensured the product meets their quality standard (whatever that may be). If you buy direct from a manufacture you do not know you have no way of knowing what quality standards the product meets...seems like a pretty big risk for something that is so important to your safety while diving.
