I had a very good experience with Meike Battery Grip for Canon. The product does not disappoint, everything works, both dials that display the camera for both batteries, as with Canon goes. The only difference to the original: the lack of joystick. If that 100, - Euro is worth, the original should purchase. Otherwise, well thought out, the opened lid of Sony disappears into the bay, the planking is ok. I recommend. Note: When storing the camera Remove the batteries, the sensor is otherwise to voltage and aging naturally much faster. It is better if the power would shut down completely with the switch would. Therefore, a star deduction.
