I have the grip and I connect it too often and also I use it to charge two batteries inside it if I am on safari. Very useful and very strong.Thanks, as I wrote, the day before the premiere of the new firmware, I bought the Z8. I film sporadically, so I hope the z8 won't overheat. When taking photos from a tent or mobile home, I'm going to try to power the camera from a power bank. I would like to buy Nikon MB-N12 Battery Grip for special occasions. I just hope that I won't break anything by connecting and disconnecting the Nikon MB-N12 Battery Grip to the z8 too often.
