K&F ConceptClip-on Filter 52mm CPL Filters Polarizing for Phone Clip

Fits nicely with strong clip. It comes in a small clear case. It is a good quality product which polarises but adds a brown cast to the photos. Great customer service. Following a mediocre review they offered me a full refund!

Good item did a good job but wouldn’t work with my iPhone 16promax because of case

Filming videos through the windscreen of a car you usually end up with quite distracting reflections, especially driving along a tree lined road with sun flicker. This lens filter removed 90% of windscreen reflections and in parts of my footage it looks like there is no windscreen at all! Now, I've read the one star reviews saying it doesn't work, but that's because the user doesn't know how polarising filters work. They have to be rotated to give the desired polarisation. If rotated to the "wrong" position the glare increases, but if rotated to the right position, the glare all but disappears - and that's why the lens is rotatable! But the effect is difficult to see with today's monitor screens, even on a large screen cellphone. So it requires some sacrificial shots that you can view on a large monitor. In my application with the clip upright, the lens was rotated such that the two grooves were horizontal, and that cancelled out 90 percent of reflections. Perhaps try that before misleading would-be purchasers with one star "do not buy" reviews, which are very misleading and annoying.

Initially was impressed with item , on a recent photo shoot the lens fell out of the frame, picked it up and reattached. when preparing to retake the photo it dropped out again. the item was in its protective case before use

Great for tattoos

Could not see a discernible difference so returned it for a refund

Good

really does make such a difference to photos!
