Of the two packs, I put the first on the camera lens of my Mavic Mini and the whole 1/3 will not stick. No matter how hard I pressed, it turned out that a part did not stick to the glass. This of course affected the photos and videos so I took it off (in fact it practically slipped off by itself), threw it away and attached a second one. This one was just as bad. I put the protectors on my DJI Spark, Osmo Action and Osmo Pocket. No problem, so no user error. I am now choosing another brand for my Mavic Mini. Do not buy this if you expect it to work as advertised.
