I got the K&F Concept Premium Lens Guards for my Insta360 X5 because I had cracked my X4 lenses in the past after a fall and don't want a similar issue with my X5. This set comes with two guards in a small protective case, which makes them easy to store and carry.The guards are really easy to attach, just place them on the camera's lenses and twist to lock them into place (make sure the notch on lens guard and insta360 X5 is aligned), and then X5 detects them automatically which is very convenient.I tested image quality with and without the guards, and while normal photos look fine, I did notice glare around bright lights, especially indoors or in strong sunlight outdoors. It’s not terrible, but it’s noticeable. Other than that, I didn't see any issues with image quality.Since Insta360 now offers affordable and easy self lens replacements, I don't plan to use these guards all the time. Instead, I'll save them for specific situations where my camera might be at risk, like when I'm hiking near rocks or in wooded areas. They're perfect for protecting the lenses from scratches and bumps in those situations. The carry case makes it easy to bring them along in my kit for such trips.They feel a little pricey for what they are, and since replacement lenses aren’t too expensive, I think these are more of a “situational” accessory than an everyday one. Still, if you shoot in rough environments and want peace of mind, these guards are worth having.
