I've had a Blackburn helmet mirror for just over a week now and am generally impressed. I find I'm using it in combination with an occasional full head turn - particularly useful on straight busy roads with occasional parked cars. It is taking me a little while to get used to rapidly changing focus but it seems to becoming more natural fairly quickly. I don't find it a major problem adjusting the position for best view - literally a few seconds. The only minor problem I've had is the mirror moves under air pressure at much more than 32 mph, but as I only reach such speeds on the occasional hill I don't find it a major problem, and could probably tighten the adjustment screw anyway...

The big question is can I fix a red LED to the front to make me look like a borg
