Charging case with custom designed Decal. When I am out on day trips I swap for the camera grip, and I just got a broken camera grip for $18 on eBay and made a 52mm Lens/Filter cover for the phone
I am also using the speck shell (white) and i took the wireless charging cover apart and put it inside the speck shell so it will charge wireless. Works awsome..
I jump between the wireless charging case, camera grip and nothing. Phone feels awesome with nothing on it but the cases add things that I use all the time
