Exemplary Rear View and Stays Put
This mirror is large and gives a nice, big view of the road behind you. The stalk mechanism used to position it is easy to maneuver and holds the mirror in place where you left it, even over bumps, etc. Securing it to the helmet vents with cable ties is simple and ingenious; much better than adhesives or flimsy clip-on mechanisms.
I have two nit-picks, which cause me to give it 4 out of 5 stars:
1. The flexible stalk used to extend the mirror off your helmet and hold the mirror in place is too beefy. It’s roughly the diameter of my index finger. That large stalk blocks some of my peripheral vision, and I find it a little hard to see things on the road off to my left, especially while making a left turn. I’m getting used to it; it’s not a deal breaker. It’s like driving car with a super-fat A-pillar though. Going around corners to your left is a little unnerving because the big stalk can block your view of potholes and other things on the roadway.
2. Despite the huge stalk that holds it securely, I still find I have to adjust at the beginning of every ride. I’m pretty sure I’m not bumping it on anything between wearing my helmet, and my helmet seems to go on the same place of my head each time. I expected it to be like the mirrors on my car, which never need adjustment after I dial them in. Again, not a deal-breaker, just a nit-pick.
Overall, the view of the road behind is so awesome, I would definitely buy it again, even with the minor issues mentioned above.

Big, Bold and Beautiful to use
...Wow!! What a difference a day makes. This mirror is awesome! I love this thing. As I approach 60 I am finding that I just don't have the flexibility on a bike, and in general, that I used to have. Turning to look back while riding used to be easy but not so much anymore. And when you are riding into the wind and it's blowing past your ears it can be impossible to hear a vehicle coming up behind you. Too many times I've been surprised by a passing car and I don't like feeling so vulnerable.
With this mirror there are no more surprises. I can't believe how much difference the mirror makes while riding. I can see everything coming up behind me with ease. After all these years riding without a mirror, I'm amazed at how stupid I've been being so blind to traffic from behind. It feels good feeling so much safer now while riding. I will never ride again without being able to see what is coming up on me from the rear. It's not safe doing so and with this simple technology there is no reason to ride with unnecessary risk given the numerous hazards we already must contend with.
II highly recommend this mirror. It's big, I really want to stress that, so don't be surprised. But it is lightweight and very stable when mounted regardless of road and wind conditions. Once you position the mirror the way you want it will not move....

The Best Rear View Mirror and Worth the Price
By far the best rear view mirror I've ever had, whether helmet-mounted, eyeglass frame-mounted, or bike-mounted. Mounts easily with the provided Zip ties through helmet vents. It provides a large, rock-steady view to the rear. Does it look dorky? Yeah, but so what? Safety first! I've had several over the years, and have grown so dependent on it that when I walk helmetless on a sidewalk in town, I instinctively glance up and slightly to the left to see who's behind me. Call it "phantom mirror syndrome"!
One word of caution: Be sure to pull the arm out of the base plate socket and store the arm-mirror component safely when you're not wearing your helmet. I lost a mirror recently because I neglected to to that when ferrying my bike through a train station, my helmet banging around loosely from where I'd hung it on the bike. It takes a significant amount of force to dislocate the ball from its socket, but it can happen, leaving you woefully mirrorless.
