Have the battery grip ordered and at first glance everything seemed perfect. However, on the second day refused the trigger service. Sent back, get new grip, the same phenomenon, this time working the trigger + - 3 days ago until he quit the service. Double Flop .... doubly acidic. The peculiarity that the LED I flashes to the camera from time to time also may find. In my opinion, the thing is not 100% compatible with the camera. In one of the first sets of instructions indicates that if unscrewing the part, and the handle starts to smoke or stink, you should unscrew it as quickly as possible. Although I found the sentence disturbingly, he was kind of funny. Not any longer longer ...
