Reduces glare and it fits well
Fits my dashcam perfectly and does exactly what I wanted. It noticeably reduces glare and reflections in the footage, especially through the rear glass. Easy to install, good fit, and a worthwhile addition to the camera.

No difference. Don't bother.
I love my viofo dashcam, and the filter for the front cam is a must, But this filter did nothing for the rear cam. I looked very closely at the before & after videos. No difference at all. Don't bother with this one.

A must if you want good quality image on the rear camera of Viofo A229 Plus.
Great accesory for the rear camera of my Viofo A229 Plus.

2/5
Everything is fine, but there wasn't enough adhesive; this left a large spot without glue, causing a "rainbow" glare on the recording that makes it almost impossible to see anything. I missed the return window, so be careful.

Does the job
This worked for my generic Apple CarPlay/Android Auto aftermarket head unit front dashcam (this camera is integrated on the head unit). After applying the filter the colors look way better and not washed out. The clarity has also improved - I could legibly read some license plates after reviewing SD card video footage. The visuals look about 25% clearer with the filter. Easy to apply and does the job.
