"Excellent Product"4.0 starson by expire10
Pros: It makes the rumble feature a little better. A long lasting battery life between charges.
Cons: Long charging time (Recommend getting Quick Charge kit if you are not patient). Makes the Wireless Controller into a Wired Controller.
Summary: I play Halo 3 and the only time I play good is when the vibration is strong. Ever since I bought this product, I have seen a vast improvement in my gameplay.
