Mounts do not move once you put them on. I tried peeling it off the next day and you can't do it! This is some crazy strong adhesive
I have multiple helmets so I bought another set of mounts and let me tell you, these things are SOLID! Once you slide your Domio into the mount, it is super secure. The Domio doesn't move around at all when riding.
I bought a whole bunch to put one on each of my helmets and also to have some as backup.
These things are not coming off. Stronger than my GoPro mount.
I have a peculiar helmet and these mounts conform right to it! I thought my helmet may be too extreme for these things to work so I put the mounts that came with my Domio on my more normal helmet. I bought some extras to try and it worked great!
All you have to do is peel off the back, stick it onto your helmet, wait 30 minutes and your good to go. The Domio slides into the mount and is secured really snugly so I am never worried it may come off.
