NEEWER4 Pack ND/PL Filter Set Compatible with Insta360 Ace Pro 2, ND8/PL + ND16/PL + ND32/PL + ND64/PL Neutral Density Polarizer Polarizing Filter Kit Snap On Action Camera Accessories, FL91

They do their job at a decent price. Recommended.

I think the footage coming out of the Insta360 Ace Pro 2 is amazing, and wanted to make it look even better, so decided to order this set of filters, and I have to say, I am totally blown away by the quality. Not only of the filters, but also the image quality I am not achieving with them. They are easy to install and remove, just twist off and twist on, and the ND filters has made getting better looking footage in bright sunlight even easier to get with more dynamic range. Using the polarizing filter has let me get good footage on water, as well as looking through glass, as it minimizes the reflections. Very useful. The filters themselves appear to be very nicely made and the glass seems very high quality as well. Overall, I am very pleased I ordered these as my videos now look even better than they did before because of these ND filters.

This set comes with 3 ND filters and a Polarized Light filter. I've been using the PL filter often and on occasion, the ND filters. They do the job nicely and get me the results I'm looking for. The fit is good and they hug the lens but could be tighter in my opinion. Otherwise, these are great to have on hand for the times you need them.They come in a compact case that keeps them safe and is easy to throw into a bag or a pocket to take along with you.

I was planning on a 4 star rating, but the magnetic lock of the case tipped me up to 5 stars because that's one less plastic clasp that can break rendering a case useless, well thought out design and an excellent stays in place snug fit for filters in a soft feel case interior with finger grip notches.I will add some ND filter comparison pics when I get some time to catch the actual low amount of clear day sunlight here in beautiful WA state, but I've seen enough shifting clouds sun shots that tells me the ND spread is effective. Will expect to test the blur effects possible with adjusting shutter speeds and aperture as well as motorcycle riding season is getting closer. Don't really have much to say about the PL yet as I am waiting for bright light while I'm at a lake, I'm accustomed to circular polarizers to dial the effect in, so I'm curious how this will work. If anything fails to perform, the rating will go down.With the Ace Pro 2 having a rubber ring around the lens cover, you'll have to remove this, it's not an issue and easily fits back on. I don't keep it on myself just not to wear it out, but I would put it back on if I were to go underwater with it, just in case that's why it's there. The filters fit perfectly snug over the lens cap and are easy to apply and remove.

I agree with another review on this same product. This DOES NOT fit snug & secure and the instructions are intentionally VAGUE, regarding the need to keep the Ace Pro 2's rubber seal in place or not. I opted to smush the rubber seal under this filter in order to create some "friction" to hold it in place..The Insta 360 Filter seems to have a similar attachment routine and it also seems just as "VAGUE".

Perfect fit for the Ace 2. If you are someone that is into running filters, this is a great addition to get the look your prefer or have more versatility in your environment. Super easy to use and great quality

Easy to install and use. These filters fit directly in place of the existing protective lens to give you the darkening you need.

If you plan on using your action camera for what it was intended for, this lense will absolutely fall off of the camera. It only gently snugs onto the existing lense with nothing to lock it into place which makes it fall off at the slightest bump or if you accidentally touch it wrong. It's not very snug, but i will keep it to use for my vlogging videos that don't involve anything extreme. I can't speak on the video quality as I haven't been able to ride with this item yet. I'd spend the extra $50-$60 to get the name brand version that's meant for extreme use. You get what you pay for in this instance.Used mainly for motocross riding and jumping.
