VIOFOCPL Filter Anti-Glare Circular Polarizing Lens for A229 Series / A329S Series Dash Cam Front Camera

Good fit on the Viofo 229Really cuts down on the glare but only slightly on the light at night.So, it's a very nice accessory to have as it improves the picture from your dash cam substantially.

Using this polarized filter helps eliminate any and all glare when driving even directly into the sun. Highly improves picture quality preventing sun spots.

Great addition to the viofo dash cam. Really helps cut down on the harsh sun glare

Indeed as description claimed, it improves color saturation, contrast, and reduces window glare. When I first carefully put it on it ended up falling off within minutes.. but on 2nd attempt I twisted it into place and now it holds tightly, no issues falling off after close to a week.I took a star off because like others have said, this feels like it should’ve been included with the a229-plus dashcam (it’s included with the 4k version) or pre-applied to the lens.. seems like a bit of a money grab.

It was one of the most recommended things to buy with the camera. It's supposed to improve the image quality because of glare and such. It installs on the lense securely. I like it.

It works well with the lens on

Paired it with the A129 Pro (2K). Fits well and there was no instructions, but there is a little line on the lens and on the dash cam so I assume I just had to align it. It does make the picture quality more clear and better contrast, overall. Also, it helps with low light glare from headlights to be able to see license plates better. I do recommend it. Wish it came with it automatically, but only the 4K version has it in the box.

This is an excellent way to block glare from your dash cam. Came standard with my Viofo A229 Pro, it works great, just line up the white dot on the filter with the white dot on the camera, its press fit. Recommended.
