Upon receipt, I also immediately compared it with my other controller, which was attached to the PS3.
The imprint on the bottom is absolutely identical. The Sony logo is correct and also the CE logo is there. On the scale provided the same picture: Both controllers weigh on the gram exactly the same. The battery life of the controller is as long as that of the other. The response of the analog sticks on Results feels exactly the same to, just like the pressure points of the keys. The Sixaxis controller is functioning properly.
So Make sure when ordering to the term "Ships from and sold by Amazon", then you should in this case be on the safe side and can safely access.
To Delivery:
The controller comes in a welded plastic wrap, unfortunately without charging cable.
For controller itself:
When DualShock 3 you can not go far wrong actually. He is very good in the hand (subjective impression), although larger controller I was previously accustomed. All buttons function properly and have a good pressure point. The analog sticks and the Digitalpad work accurately and the battery life is also in operation for a long time. The vibration effect also works great, is stronger than the alarm of a mobile phone, for example. So noticeable, but not annoying. The Sixaxis controller I previously had no problems.
Negative contrast is the form / nature of the analog sticks. Once the hands are slightly sweaty, it can happen because of the convex shape, the thumb slipping off the stick. Especially with games where you permanently running in either direction and stops chosen the stick, which can happen from time to time. The same problem with the convex shape can be found at the trigger buttons L2 / R2. If these longer need to be kept, you can slip in advance and will have to start again.
(Note: There are attachments for the controller with a concave shape to buy, that should fix the problem)
Conclusion:
Actually, the controller would have deserved 5 stars, the devaluation of 4 stars there because of the convex analog sticks and trigger buttons.
