Here is a quick video review of a lens cap for the Nikon Keymission 360.
The Nikon Keymission 360 is waterproof and even shockproof without an external housing. However, its lens can still be scratched. Mine got scratched, making it look foggy on one area of the one of the lenses:
|The fogginess on my face is not a "beauty filter" but because the lens got scratched!|
In summary, the Koroao / Holaca silicone rubber lens cap works reasonably well. It fits the Keymission 360's lenses, although it is possible for the caps to be dislodged if they are bumped. I would definitely suggest getting them if you have the Nikon Keymission 360 to avoid scratches. They're available on Amazon (Koroao here and Holaca here). If you'd like to get them, I would greatly appreciate it if you could use the Amazon links above, which would help support 360 Rumors at no cost to you, so I can do more tests and reviews. Thank you very much.
BTW pls. note that the caps I got were mailed from China, so they might take a while to arrive.
