While I agree with the previous reviewer that Sony could have made better provisions for charging, this grip is the perfect companion for the new a7 II body. Coming from the bigger DSLR body like a77 II, the smaller a7II body felt small and sometimes a little clumpsy. Adding the grip not only increases usability, but provides a better grip of the camera especially if you have big hands. Another plus is the extended battery life. I bought an external charger and charge the batteries separately. For the price I am considering buying another charger So i can charge both batteries. Great product!
