VIOFO CPL-100 Filter for A119M Pro, A119 MINI 2, A129 Plus/Pro Duo, A119 V3 | Anti-Glare CPL Filter For Front Camera, Reduces Reflections and Glare, Enhances Color Saturation, Easy Installation

I had originally wrote a different review that Amazon apparently did not like, but thankfully I figured out the issues I was having. My original review focused on the filter making the image blurry and having to deal with the rainbow circles like others on here. I have since figured out both issues. Starting with the blurry, there was a protective film on the inside of the lens that I somehow missed and I feel stupid for not noticing it immediately. Now the big one. The rainbow rings, at least for me, were caused by having the static sheet be partially in the camera's fov and the way light was diffused caused the ugly colors. Now that both issues are fixed this is a wonderful filter that really does help to reduce reflections from my dashboard and makes the image look nicer.

This polarized lens is a must-have if you’re using a VIOFO dash cam, especially during daytime driving. It noticeably reduces windshield glare and reflections, giving you clearer, more detailed video footage. Pros: • Reduces windshield glare and dashboard reflections • Improves image clarity and contrast, especially in bright sunlight • Simple to install—just clips on and stays secure • Adjustable rotation to fine-tune polarization angle for your setup • Protects the actual camera lens from dust and scratches Cons: • Slight darkening of footage in low-light/night conditions (expected with any CPL) • Adds a bit of bulk to the camera profile—barely noticeable, but worth noting

It works. Cuts down the reflective glare from the dashboard and bright lights. Just snaps on

It was quite easy to install the additional lens for the VIOFO Mini V1. The video quality doesn’t decrease during recording, but it can be a bit darker in low light conditions. While functional, it gets the job done and was easy to install by clipping it to the camera. Be aware that it offers good value if you want to reduce glare, but since the plastic is thin, those who may be clumsy might break it.

Working well so far on VIOFO 119 Mini 2 camera. Does what a circular polarizer is supposed to without too much effect on exposure value.

Works great for daytime video!

I have used a VIOFO dash cam for about a year now and this polarizing lens really makes a difference. It really cleans up the image. Spend the few bucks this cost. Otherwise you will look back and wish you did. Be sure to get the extreme duty Sd card since the cam is doing a considerable amount of writing. The lens cover is a quick and easy install.

100 percent needed for the dash cam. I tried it without and the glare from the sun made it difficult to see some of the video. They should include this or add it to a bundle.

I received an open box product. It was clearly used as I could see finger prints on the lens too
