Familiarity: I've put it through the wringer
I bought one of these in mid-July 2013 to replace a Bell Volt helmet that was four years old. I was very impressed with the fit as I had always worn Bell previously and wished that I had made the switch earlier as I felt that it had a close, yet still comfortable fit on my larger head.
On August 6, I touched wheels with a long-time riding partner and lost control of my bike at 21 mph. During my fall I went off the back of my bike, hitting the ground and my head snapped back hard enough to knock myself out. I got a pretty good concussion and spent the night in the hospital for observation. The inside of the helmet foam fractured in several places accepting the energy from the impact but interestingly the exterior was still in remarkably good shape. I was extremely lucky in that my other injuries were relatively minor.
I had worn this helmet probably only 10 times before the accident, but given what I know now,I am certain that it saved me from a much worse injury and I think it protected me better than my Volt would have based on the fit, especially in the rear. While waiting for my hospital discharge papers I called and ordered a replacement! Love this helmet!!!
