I could be very wrong, but I consider myself to be the typical old man, get the camera out and hour at a time, kinda guy. I have never had problems with batteries not giving enough, or a problem carrying an extra battery in the case I think I might be doing a whole lot of shooting. I know some of you go through batteries a lot. I just think that most people are already happy. I am. I even have trouble justifying an OEM extra battery grip for myself. I have not had one since I had a 70D.
