There are different ways in discerning a fake from the original and one of them is ;

Without the console nearby or switched on ,count the duration of number of times the indicator blinks ,if it's more than 30 or below 30 blinks just know you have a fake

The colour and position of the serial number stiicker at the back of the controller , it should be dark and the numbers boldly written.

The size of the home button and how it is written on the button.

I would say the weight of the controller but these days a lot of fakes tend to put metals or make the vibrators in the pad heavy but if the controller is light, run o

If there's a hue of light under the controller while it's On then you have a fake.

Try pairing it with your mobile device using the share and ps button , if it doesn't pair orbit pairs and disconnects,you got a fake

If you are brave enough unscrew the controller to check for the battery, the buttons and see if the battery carries weight and the placement of the battery holder

If the buttons are greyed out , this doesn't actually apply to the V2 controller

If you are worried about getting a fake irrespective of what it looks like, try getting licensed playstation 3rd party controllers like the scuff,Nacon,kymo,razer

If you have anymore suggestions or disagreements kindly point them out.

Have fun
