Thank you for viewing. I am selling this item to organize my equipment. I purchased this as a spare and carried it just in case, so it is an opened item. It is for HERO9, but I believe it can be used with models of the same shape. I had prepared this for my HERO11. Please refrain from purchasing if you are sensitive to used items, as this is an opened item. (Search terms) ADIOD-001 GoPro Replacement door Battery door HERO11 BLACK HERO10 BLACK HERO9 BLACK Genuine
