Insta 360 X4 Premium Glass Lens Guard Set Screen Protector for Insta360 X4 X 4 9H Hard Tempered Glass Film Anti-Scratch [Bubble Free]

I ordered this set for the glass domed lens protectors. I already have screen protectors on the touch screen, so I will hold on to the ones that came with this set until needed.I noticed another review that said these lens protectors did not lock onto his camera properly, but both of them locked in firmly on my camera. It did take a little more turning pressure to get them to snap into place than it took to remove the original protectors, but not much more. I used my thumb nail to turn the knurled ring until it locked into place. No tools needed.I have not noticed any differences in the image quality between these new protectors and the factory originals. I scratched one of the original protectors but decided to replace the pair to ensure identical image quality on both lenses.I am very happy with these lens protectors.

Junk don’t buy wasted my money doesn’t properly lock onto lenses

Both the lens and display protectors are great, perfect fit, perfect image and perfect touch sensitivity, can't complain about anything. Will last until smashed hard.
