Prinzipiel is the difference between the original Sony controller and of Hama not too big but it's the little differences noticed the negative. 1. The cable is slightly shorter, that bothers me personally can not but the typical "bed on the other side of the room" user doom are (Cable length ca 1.80 m to 2.00 m ... the original ca 1m longer). However, shorter cable is a small plus for the longevity of the cable. 2. The keys are slightly higher, thus the response time is greater that especially in games like Soul Calibur and Tekken and all games with fast key sequences hindrance (A bit like the difference between an old office keyboard and a laptop keyboard) is 3. This is a personal problem but what can tap poor workmanship. After about a month responded to me the arrow left key much harder than the other keys.
Conclusion: A little money saved, but less quality. Who, for example, Final Fantasy plays for the controller is completely sufficient for quicker games is an original controller comfortable.
