Who here knows dualshock-Ah 3 and their fakes?

In General bought in a game shop honeymoom DualShock 3, according to the seller it is original, but I doubt it, you know what dalchoki marked CECHZC2H is a version for Hong Kong, but what does a2 do not know

even alarming lack of certified badge although I have never seen DualShock marked CECHZC2H and sign certification MB the fact that in different countries these icons are different, but then it is unclear what it means to Compilies with IDA Standards DB102988 and as for the Board on all videos with the original ballokume 3 I found it closes a stick, like they did to it is soldered, but as I can see in the pictures



MB is just what some second or third revision of the ds3 which changed the location of the innards or in versions for Hong Kong as it should be, or is it a fake?
By the way if you shake it at all no noise
