Thinkware CPL Filter

My Thinkware dashcam wasn’t very useful until I added this filter. The dashboard reflected off my windshield into the video so badly I couldn’t see much. The filter eliminated both the reflections from inside and any glare coming through the windshield. No brainer purchase.

Thinkware please make the CPL filter standard on every dashcam.

Really nice result with the filter, it keeps the glare and reflection at minimum. I bought two, one for the front and one back. Only drawback is that you will lose some light, as expected. In day light there is no problem, but with the filter and window tint in the back it get very dark (still manageable!).
I was worried about the adhesive, but I was wrong, had some 32°C day and it didn't budge. May seem expensive, but it's worth it for the better video result!

The filter is easy to install and improves the image quality.

Noticeably cuts down on glare and makes recording much clearer. You might notice a bit of brightness reduction if placed on a camera behind tinted glass but can be adjusted if you have a rear camera with light settings. After orienting the filter to the lens, take your time to align it as close to center as possible or else you might end up seeing a bit of the tape surface during video playback. Highly recommend this lens and now use it for all my vehicles.
