outstanding product & read the instrutions first!
Outstanding product! Far as adding the lense to the dash cam, it is very simple and easy to do. Just read the instructions very carefully and take your time. Make sure you have a good light source and mark the 2 points before you attach the lense. it makes alligning the points so much easier. I used a permant marker on the clear platic lense cover and had no issue allagning it up corretly the 1st time. NOTE: On each side of the lense filter there is a plastic lense protector cover & out of the box that needs to be peeled off before sticking to the dashcam. One side is clear and the other side is blue, the colored side goes on the dash cam lense. Make sure u keep ur finger prints off the inside lense, it is very sticky. Trust me its simple and quick stick once its on the dashcam. My overall review with the dash cam filter lense on my dashcam. the glare and the reflection of the dashboard and windshield is gone. This is at daytime and at night time and now i dont get the curve dashboard effect when i reviewing video. Far as the quality of the video, (NOTE) so far i only reviewed it on my cellphone and NOT my pc. I get better quality on my pc when i reviewing old video. cellphone only: day time, the quality is clear, nice and crisp and outstanding quality video. Cellphone only: Night time: the video seemed a little gritty & dark but again i am NOT a expert on video quality and etc. i have not spent endless hours comparing before and after video (with & out the filter). So this my quick review due to i only spent a few miutes reviewing video only to see if there was a difference and YES there was! Overall for $20 on amazon & It was worth the money and i got no complaints about the filter. The quality is outstanding, all the glare and windshield reflection is gone and that was i was looking to get done! I am very happy i got it!

Exactly the fix I needed
This helped reduce the amount of light scatter on the rear of my dash cam during night driving. Headlights behind the camera would just overwhelm it and all you could see was the bloom from the light. With this filter, that bloom was reduced and now you can actually see what's going on in the video.

Works well
I put this on my front camera as it's more important for clearer video to me, to test it out. 2 weeks on, works great...noticeable difference in clarity and reduced glare compared to the rear video. I will purchase another for the rear camera now...i just wish the price was better. This is too expensive for what it is. I can purchase specialized sets of FIVE of these for my phone camera lenses for half the price. The 1 star is off for that pricing knock.

These Filters Work!
I added these filters to my Thinkware Front and Rear Dash Cam Application. They made a definite image improvement for both cams.

Ghost rainbows if you have tint
I haven't decided yet if this filter will stay on my dashcam, or if I'll toss it. I do like the idea of it, but the execution is lacking. I have ceramic tint on my windshield, and this filter acts much like polarized sunglasses do - it cuts down reflected glare adequately, but leaves prominent ghosted rainbows on the image. I thought maybe I had the alignment slightly off, but after double-checking, the vertical alignment notch is lined up as the directions specify. I wouldn't buy this again unless it was for an untinted vehicle.

I installed it in my Thinkware F800 pro and I didn't see any improvements in video quality or removing the shades/glare.

Does a great job at filtering out glare on your recordings.

Easy enough to install, it does sharpen the image, and helps with glare.

Cuts glare down but loss of quality in picture. Still worth it for the glare cutting.
