In terrain there is often the case that the GoPro is dirty because mud injected to the lens. The lens then clean accordingly is inconvenient and brings road no satisfactory result. Here, the manufacturer lens cover has come up with something nice: superimposing fixable films that you can simply pull off the road when dirty. Tip: Check out the video (link in the comment). A small suggestion would be to affix on the packaging a QR code that allows you end up immediately in the video. The specified link is very long and it is pointless to retype it. The films, with and without foil are indistinguishable. Very nice!
MY CONCLUSION: Great Idea! Just two sheets superimposed fix (once Pinockel left, once Pinockel right) and simply pull off the dirt road, you've got a clear view again. Excellent!
