Review on GoPro Anti-Fog Inserts: Ensure Clear Vision with Official GoPro Accessory by Hector Mak

A great addition for GoPro divers. I've had several fogging issues with my GoPro camera in the past. Inserting one of the inserts into the underwater box prevents fogging. I was able to use one insert for 8 days of diving. I would recommend it to anyone diving with a camera. They also come in a resealable bag for easy storage!
