Vantrue 40mm Ultra-Slim CPL Circular Polarizer Filter for Vantrue E1 Pro, E1, E2, E3, E1 Lite, S1 Pro, N4 Pro, N5, N2X Dash Cam, Reduce Glare and Reflection, Enhance Contrast

Product is good. From Sellers point of View, seller is charging white elephant for the product, MRP is 2999/ seller is charging almost double of it.Beware....

This filter significantly reduces glare and reflections, enhancing the clarity and color saturation of my dash cam footage. Perfect for capturing clear views through the windshield. The ultra slim design fits my Vantrue Nexus 2x seamlessly without causing vignetting. Regarding the one star reviews mentioning image degradation and rainbows, I suspect these issues stem from not removing the protective plastic film on both sides of the filter. It’s easy to miss but crucial for optimal performance. Tip: Before use, carefully peel off the thin plastic film on both sides. Check under good light if unsure, to avoid any image issues. It took a bit of trial and error to get the rotation just right for maximum glare reduction, but once I did, the results were impressive. Overall, this filter is a great value and a must-have accessory for any dash cam user looking to improve their video quality. It won’t eliminate all reflections (e.g., from metal or in poor lighting), which might disappoint those with unrealistic expectations.

I have two Vantrue dashcams, and both have this circular polarizer. It is effective in reducing reflections of the dashboard, and increases the contrast of your videos on sunny days. This Vantrue polarizer threads onto the lens, just like the filters used on SLR cameras. The quality is comparable to those SLR filters. It fits the lens well, the threads are smooth and accurately cut. Rotating the filter to adjust it is smooth and easy; there is just enough friction to maintain its orientation on the camera.

The product that I received seems was used previously as the packaging was open. Additionally, it is defective as there is a rainbow color in all videos which always appears if I placed it on my dashcam. But it seems it works by reducing the Reflection to some extend.

Installed with ease and spun it to get the best view through my windshield. If your windshield glass or tint is also polarized you may see a pattern on the glass/tint when using this lens. When 2 polarized lenses are close to or up against each other and 1 is turned they will block all light when just right. If they don't then one or both of them are poorly or not polarized.
