Firstly, for the price it's definitely a very good helmet. It has decent claimed certification so should do its job if needed to. The fit is good for my massive peanut head(!), and the blinking LED on the rear is a great safety feature.My one real issue is the strap adjustment and retention system. I generally use high-end helmets for triathlon, costing many times more than this one, and the difference in the strap adjustment is noticeable. The strap sizing around the ears doesn't have any effective way to hold adjustments in place, and I had to improvise by wrapping electrical tape around the strap to prevent slippage. This is a one-time problem however, and doesn't affect the helmet in daily use when commuting.Overall, I'm very happy and would certainly buy it again.
