Perhaps someone could suggest a good helmet mirror, compatible with the Bell Alchera....

I used an original "Third Eye" with my old Bell V1 Pro, but with the new design I am now in need of a replacement.
I have read the good reviews on the "Bike Peddeler - Take a Look" but am unsure of mounting, and I do know that I want to stay away of the the others that mount with adhesive on the exterior.
Maybe you have some thoughts?
I'd be grateful...
