37mm CPL Filter Circular Polarizing Lens for Phone Polarizing Filter, Enhance Color Saturation, Reduce Glare, Includes CPL Lens and LensClip

Is item is quality built. Very nice! It fits perfectly over the camara lens of my Android phone. I recently used it on a trip to search for sea creatures living in tidepools. This filter was a must have. I could easily turn the filter in it's howsing, and block out most of the reflected light that was coming off the surface of the pools, so I could get great pictures of anemones, starfish, crabs... Finally, my phone camera could see what I could see with my polarized sunglasses. Sweet!

The media could not be loaded.  The condtruction was solid.But the filter was lacking. It helped reduce sharp glare, but only mildly and still had flare.As the video show, on glass, reflection is completely uneffected.This is a worthless buy be ause it doesn't accomplish anything. I'm returning mine, because even for $12 it's completely unusable.

I don't understand the negative comments. Apparently, people don't know how polarizers work. You need to rotate them to remove unwanted glare. I checked this one by rotating it relative to an expensive polarizer from my SLR. As you can see, it went black as it should. This is proof of effective polarization. Not bad for the tiny amount of money charged.

The filter clips on to my Galaxy 6 phone easily. You need to spend a moment aligning the slot to the lens and the light meter and focus sensors. It stays in place nicely. Rotation of the ring needs to be done slowly as the angle of maximum glare reduction is narrow. Picture on the right is before adjustment. Picture on left is after rotating the ring slowly until the glare is reduced . You can still see some reflection on the water but most of it is gone. This filter may be less effective than the filter I have on my Nikon camera, but even that generally leaves some glare.

I wanted a cheap quick anti glare clip on filter for my iPhone pro Max 11. I am SO HAPPY with this. It clips on easily, will not scratch or harm your screens. Also the lens rotates. So you have to rotate until you see the glare is gone. In my photos you can see the difference.

Works great as a polarizer - easy to use and spectacular results. For video however, the lens covers the microphone and things sound pretty thin.

Did not see any difference at all while on my phone's camera. I needed something to show jewelry detail while doing live sales.

This product works good andwhen showing jewelry makes it so much easier to see it. The only thing I dislike is how close up to it you have to get.

I got this after watching some videos on using it over my laptop camera to remove the computer screen reflection off my glasses. I set it up and adjusted it properly as per the videos I watched but there was zero difference in the glare on my glasses, returned. The product looked well made but did not work for what I needed.

This not as advertised, make no difference at all. Should have read the reviews.
