Great! Remember to give yourself time to get used to it. After a few weeks you'll be an expert. Tip: don't attach it until you have it in just the right spot. Then also, I've found the sticky stuff supplied tends to break down over time so I add a small dot of epoxy when attaching and that holds up well over time.
FWIW, I use the Third Eye helmet mirror and I love that one.
Good luck, and feel free to PM me if you have any trouble or questions about the mirror.
