I bought this because I was tired of unscrewing the lens cap on my 1" Insta360 every time I wanted to change the battery. Now all I have to do is unlock it and take the whole camera out of the lens and that's it, replace the battery and put it back in the cage. I feel a lot better, the camera is in a metal cage. I've bought SmallRig cages for ALL the cameras I own (four total, along with three Sony mirrorless cameras).
