I am very pleased with the purchase however, it seems that the o-ring is not sized correctly. When I tried to push the lens on to my GoPro it would not go on. I was afraid that if I forced it I might damage the GoPro. As a solution, I removed the o-ring and replaced it with a similar size from a local hardware store. I had to cut it and insert two pieces that did not completely seal the entire perimeter of the groove where the original o-ring was. It now fits very snugly without having to apply too much force. This probably voids the warranty but I'll take my chances. The glass and function of the adjustment ring work excellent. If it weren't for the o-ring issue I would rate it as 5 stars.
Use it on my Go Pro hero5 black. With the filter on, it made my photo look good. easy to fix on. just plug and play.
Great bit of kit. but wasn’t expecting £15 handling fee on top, if i would have known. Then i probably wouldn’t have bought it.
I am in love with the polarizer I received from you guys. It has transformed the video I take over the ocean. It is spectacular, thanks!
So far I’m very impressed with the polarizer filter, fits snugly and feel solid.
