This three pack from K&F Concept is an absolute essential if you want to keep your Insta360 X5 screen looking brand new. Since the X5 is built for action and often finds itself in rugged environments, having a 9H hardness tempered glass layer provides a lot of peace of mind. The custom fit is excellent and covers the screen surface precisely with its 3D curved edges, ensuring there is no gap for dust or grit to get underneath.The application process is straightforward thanks to the included cleaning kits for each of the three protectors. It goes on smoothly without any frustrating bubbles, and the high optical transmittance means the screen stays just as bright and vivid as it is without the protector. You really do not lose any of the original 8K preview clarity or the responsiveness of the touch interface.Pros The 9H tempered glass is incredibly tough and offers reliable defense against the scratches and impacts that are bound to happen during outdoor shoots. I really like that it comes in a pack of three because it gives you immediate backups if one takes a hit for the team. The oleophobic coating is a nice touch as well since it does a great job at keeping fingerprint smudges to a minimum while you are navigating menus.Cons Because these are precisely cut for the X5 screen, you have to be very careful with your initial alignment to make sure it sits perfectly within the bezels. There is not a lot of room for error during the drop, though the included auxiliary stickers certainly help with the positioning.Final Verdict If you just picked up the X5, this is a low cost investment that saves you from a very expensive screen repair later on. The clarity is perfect and the touch sensitivity remains spot on. For a high quality 3 pack that fits the curved screen so well, I definitely recommend picking these up before your next adventure.
