Owned the modular version for a few months. Is the mirror just a gimmick? No Does that make it a good helmet? No Build quality is cheap. I dropped it out of my hand when I was walking so it would have only been below waist height. Got chipped in one part and the rear view panel almost broke off at the back! On top of that, this helmet runs about a size large compared to my AGV and Shark helmets. I usually wear a size large but this thing was just flopping on my head. Probably explains why they aren't selling. Also the neck strap was positioned such that it dug into my adam's apple, not sure if it's safer to do it up or leave it undone. If you have small shitty mirrors on your bike you may benefit from the rear view system. Otherwise, there are much better helmets which can be had for a similar price.
