Hi ! I just got my hands on an Ez 3in1 and I started using it by testing all the features including the rumble. I use Rodolph tool to activate the rumble mode with my R4 and I start a game such as Metroid to test rumble. Each time I got hit, the rumble is activated *and* the power led goes red in the same time. Then, it turns back to green until I got hit again... Is this normal ? Thanks !
