Watch for fake controllers with model number CECHZC2E. It was bought from Ebay from seller: thsunami2013. They are shipped from Puerto Rico and are completely impersonating Sony.
CECHZC2E is a legitimate model number for a PS3 controller.
Shipping from Puerto Rico, just means there is an online retailer who is based from there, who got it from a distributor who gets it from another distributor who gets it from China or Japan.
What makes you think that they are "fake" ?
It's pretty common actually, had it happen to me also. My mom actually got it as a gift for me, you could just tell that the plastic felt different, and all the Sony brandings were just a slight hair off, plus, the L3 and R3 clicks were way more audible and hollow sounding. I simply told the people I bought it from that it wasnt connecting and to give me a refund and it worked.
