Review on GoPro Anti-Fog Inserts: Ensure Clear Vision with Official GoPro Accessory by Tim Larsen

Worked great. Having recently moved to Florida, I've had trouble converting from air conditioning to water. We have been to the beach with the dogs a couple of times and all my photos are blurry due to the fog. I bought them because they were offered to me and they are perfect. I know you should cook them to reuse after use, but I've only used the same one once that I forgot to take out from a previous use. It still worked perfectly. I am so excited that I bought them.
