"AData這牌子耐用嗎?", can't tell (I think you're talking about memory cards). See if anyone else could answer this question. Anyway, Rubik's Express Ltd. 憶智 is the official local distributor of A-DATA products. And their customer service is good.
For local distributors (memory card products), I would prefer GC, viewking, supply consultants, microworks, transcend hk, Rubik's Express, etc.
