I'm amazed by these lenses. I have a pair of ignitors, the Sensor Mirror, and Platinum Mirror. They are extremely durable. I spent an entire weekend riding through the glades of Jay Peak. I was expecting to see some scratches on my lenses from hitting all the branches and doing an unplanned faceplant into the ground. Not a single scratch to the mirror finished. All three of those lenses meet all my riding needs. Bluebird, low light, and night.
