Blackburn’s helmet mirror is a great idea but its susceptibility to vibration and misalignment can be extremely frustrating – especially at night.
The component parts are to Blackburn’s usual high standards. Flat glass is used to provide the most accurate reflection and it won’t fade or tarnish with age. This is set into an articulated body that's made from durable, high-quality plastics. This attaches to your helmet via a double-sided adhesive pad, and Blackburn have thoughtfully included a spare should you get the positioning wrong or need to swap between lids.
Initial alignment takes patience but turning your head about 20° and glancing in the mirror gives an uninterrupted view of conditions behind. Claimed to be a universal fit, in practice compatibility isn’t an exact science and is best with MTB-inspired commuter helmets.
There’s a definite knack to getting the best from this mirror, and I had a few outings along quiet rural lanes before I was confident about hitting the town with a laden trailer in tow. However, it wasn’t long before a quick glance was enough to see what was going on behind.
However, poorly surfaced roads caused it to blur uselessly, especially at night, reducing a procession of cars to a glimmering jumble of headlamps. Particular care was needed when removing the helmet at rest stops to prevent misalignment, although this in endemic to the breed in my experience.
Good concept but easily misaligned and too sensitive to vibration
