Perfect fit, easily elevates the footage and protects the lens at the same timeSnapping these filters on is stupid easy. You literally just press them on and they click into place with no fiddling or tools. I was expecting some trial and error but it was more of a line it up and done situation which is perfect when you’re already outside and trying to catch light before it changesThe fit is excellent on the action camera. They sit snug and centered and don’t feel like they’re going to pop off when moving around. I shook the camera around and tossed it in a bag and everything stayed put so confidence level went way up right awayBuild quality feels legit. The glass is clear and clean with no weird color shift and the coatings actually seem to work. Water beads right off and fingerprints wipe away easily. Even stacked against bright sunlight the footage stays sharp and contrast looks natural which is exactly what you want from filters like thisHaving multiple strengths plus a polarizer in one kit is super handy. You can dial things in depending on how bright it is and still keep motion looking smooth instead of blown out. The polarizer is great around water or shiny surfaces and makes colors pop without looking fakeYeah it costs more than basic accessories but you can tell where the money went. Solid materials, clean optics, easy use, and real results on footage. For what you get it feels like a good value and not something you’ll regret buying later
