I totally disagree with the comments about the poor quality double sided tape that these mounts come with.
I wanted to relocate one of these mounts to a different location on my helmet, and I could not believe how difficult it was to remove.
The key to making these mounts really stick is to clean the surface with isopropyl alcohol before hand.
If you don't, then nothing will stick permanently, no matter what type of tape you use.
As for using glue on a $750.00 helmet....forget about it...!
