First off, the metal ring and rubber lining make these filters feel premium—they click into place on my Ace Pro 2 like they were made for it (though pro tip: you’ll need to remove the camera’s silicone ring first, despite Insta360’s warning). No vignetting, no fuss.

Shooting at noon? The ND128 turns harsh sunlight into buttery motion blur for cinematic waterfall shots. The polarizer? Magic. It killed reflections on a lake during my kayak trip, and the skies popped like I’d edited them in post.

The glass is ridiculously clear—zero softness even at ND64. I once dropped the ND32 onto rocks, and not a scratch. The carrying case is bulky though; I ended up stuffing just the ND16 and polarizer in my pocket for hiking.

Worth every penny if you’re serious about action cam footage. Just don’t mix them up—they forgot to label which filter is which!
