This is a genuine GoPro designed door that is pretty amazing. ONLY compatible with GoPro Hero 11 Black/11 Mini/10/9. (FYI... Hero 8 needs a separate product, see below. Hero 7/6/5 all have built-in PowerDoor,, so nothing needed for them.) GH11/10/9 PowerDoor Rainproof replaces GoPros "SideDoor" to protect the battery and SD card. Genuine GoPro part.
Make sure you use Silicone Rainproof Putty on the cord going into the GoPro and into the PowerStick, to keep the GoPro and stick dry! (Sold separately. Click here for Silicone Rainproof Putty.)
