If you have taken a Lumia 1020, is that you certainly intend to take pictures. I want to say that it is therefore an essential accessory for a good grip of the camera in photo mode, as well as its small addition that makes all the difference: the extra battery. Perfect for taking photos all day without missing your most beautiful moments.
A little more to the Lumia 1030/1040 if there is one day ... on the Grip, add an external memory. It will thus have three uses (comfort, battery and memory). Hoping that ... :)
