K&F Concept CPL Filter Compatible with Insta360 Go Ultra Action Camera Accessories, Anti-Glare Remove Reflection HD Optical Glass with 28 Multi-Coated Filter
SKU: KF12.0011
Nice filter! I picked up just the CPL (polarizer) filter. Everything about this is as advertised; it's got a metal frame with ridges for grabbing on the side, with a smaller threaded aperture to attach to your Go Ultra. I've confirmed with another polarizer lens that it is polarized, and you can definitely tell it has anti-reflection coating on it. The case it comes in is resealable, and easily opens and closes on demand while staying shut in a camera bag.
It's currently priced for $20 and I think that's a fair price for a quality lens.
