They work! Who'da thought?!?
These little devils actually work to reduce glare. At first I was a skeptic but after installing it, I'm sold.

Does the job
I didn't have much glare. Now, I don't have any. Adjustment was easy. Added bonus is that the filter protects the lens. Didn't really need this. However, a nice add on and worth the $20.

Works as advertised, almost a necessity.
I wish I had ordered this when I bought the camera. I installed it quickly, following the instructions, & it works great, just as advertised. (Maybe incorporating this into the camera pkg would be nice?)

Real 1-Year Update: Easily the best CPL filter I've run in my Ram
I’ve had this ROVE circular polarizer mounted on the dash cam in my Ram for over a year now, and it is still working flawlessly. Having owned a few different brands of dash cams and filters over the years, I can confidently say this one is the best so far. If you drive a truck with a massive windshield, you know how brutal glare and dashboard reflections can be on your video files—especially on bright summer days. This filter completely cleans up the footage, cutting out the glare so you get clear visibility of the road ahead. It threads on perfectly, matches the lens geometry cleanly, and the anti-glare glass hasn't degraded or clouded up at all after four full seasons of direct windshield heat. If you want a dependable lens filter that actually holds up to daily driving, this one is an excellent piece of gear.

Excelente
Se coloca súper fácil en la cámara, no requiere desmontarla, con girarla un poco se puede poner. Me gusta la fotografía y siempre uso filtros para proteger la lente.

Waste of money
Eliminates 60-70% of the glare so a waste of money imo.
