I have 3 helmets that I use. Can I use this device on different helmets? If so, is interchangeability simple?
In short, no. Two reasons: first, the unit only comes with a permanent glue mount. You could probably come up with a less permanent solution, but it would probably look bad and be more bulky. As it is, the separate battery system is what allows for such a low profile unit. Which is your 2nd problem. Since the battery is separate, you would have to find a way to bury the battery in another helmet inside the liner. It's a great unit paired with the Shark helmets it is intended for. I personally wouldn't recommend trying to use it in non-Shark helmets, especially if you plan on moving it around which would require a special mount. See my review of the ST for photos of how this works and looks.
