FiTSTILL 24PCS Anti Fog Inserts Reusable Moisture Absorbing Strips Humidity Removing Defogger for Go Pro Hero 13/12/11/10/9/8/7/(2018)/6/5/4/3+/3 Session Max Action Camera Underwater Dive Housings

Took these to use in a ProShot case for an iPhone. It was plenty humid in Tahiti and we didn't have any trouble with fogging.

I bought these for a Caribbean trip and they work. The first snorkel I forgot to put them in the dive case and after a short while in the water the inside of the case fogged up to the point that it looked bad in the pictures. Subsequent dives I used the desiccant strips and had no clarity problems. I did find that if you keep the dive case closed between uses that they are good for several dives. I would open the case just long enough to get the camera out and close it back up until the next dive. I think I got at least 4 dives out of a set of strips.

listing does not give measurements. these are 25mm x 10mm packed in packets of 4. for reference I'm adding a photo which shows this product relative to the insta360 dive case which I bought this for.although they don't fit, they can be used in the dive case - just put them by the sides of the camera without obstructing the buttons. used on a recent trip to Cozumel and did not have fogging issues, just not the ideal form factorthey did not seem to get as damp as the insta 360 strips. not sure if that's because they're not absorbent, or are can tolerate more moisture

I tired everything to keep the Rylo360 camera from fogging up inside the waterproof case. That camera gets so hot, no matter what I did it would fog after about 10 minutes of filming.I put two of these anti fog inserts in the case the night before and no fogging at all! I filmed for 30 minutes straight. It's the first time this camera hasn't fogged up on me.Totally worth the money. You can reuse them to. You just have to dry them in the oven. Use over and over again.🤙

These pads definitely helped absorb the moisture within the camera case. Used them for my GoPro while diving in Cozumel.

I teste today under water with my gopro hero 8 black and wait for the camara to warm up to see if it work and right now is working good. I teste test it on my house becouse I have a vacation in May and I want to make sure it work before I leave for my vacation. It work. I will give a up date ones I come back.

i have used these on at least 95 ft dives and they worked perfectly every time.Great product , just ordered more

Really work well for scuba diving and making sure their is no moisture in the case. Word of warning though, if you’re bringing these through airport security just keep them in the packaging because I didn’t and TSA thought they were drugs.
