Pro Shot Tidal Mask Anti-Fog Film Replacement x2 Long Lasting Anti-Fog Protection for Snorkeling and Diving

works great. would highly recommend it to anyone

Used them on my first open water dive in the Maldives. I cut them to fit my scuba pro mask and it worked like a charm. Recommended.

the lenses were way smaller than the ones that came with the mask so that’s a little annoying. I wish they were the same as the ones that come with the goggles because those worked great.

These are useless. There is no way to practically apply them accurately. I tried to apply all three sets of films with slightly different application techniques to try to get them to work with no success. Given the recessed nature of the lenses there is no way these would ever be practical. Accurate placement is just stupidly impossible. Just resign yourself to the fact that you will be using antifog instead if you purchase the mask these are designed to fit. Don't waste your money.

Tried so mane different before Tidal , they are so - foggy ..Tidal = superDominican Republic, La Romana, Catalina island3 m deep - can see from surface, everything, so clear , so perfectjust remember - follow the instruction - take care of the mask , soap, cleaning and you’ll be amazed the pleasure of snorkelling ..Cons:install application- a smaller then originalinstallation - very tricky and can not be perfect !!plastic on mask start cracking in half of year .. - still ok to use .Thanks Tidal !!!
