4.0 out of 5 stars Worked great for snorkeling., July 17, 2013

This review is from: FogFree 15 Anti-Fog Inserts for GoPro HERO4 HERO3+ HERO3 HERO2 (Original FogFree) (Sports)
These did the trick in a GoPro Hero 2 Dive case. Added two as the instructions stated and each set would last for about a day or two with no fogging up. Took it in and out of A/C, snorkeling, beach, shade and sun, NO fogging at any point. The only thing is that they started to look like ratty cardboard quickly and they generated some dust- That doesn't seem to affect their usability though. I would agree that they need a color change when they're activated or spent.

MAKE SURE you activate them in an oven before the first use! It would also help to keep the activated ones in a humidity controlled case (I threw them in a Pelican case with desiccant when not in use)
