Review on Cairbull Cycling Helmet Goggle Adjustable by Jesse Diaz

The helmet looks great and seems to fit perfectly, but the automatic tightening function didn't work on mine. The right side serrated strap (pictured) doesn't tighten like a handle when you turn the flashlight, only the left side pulls back. I can't tell if it's a design issue or if I just got a defective unit. Revolution. I have to tighten the plastic crown to fit my head so my helmet is now crooked with only the left side buckling. Edit: They replaced the first helmet, the second one works fine and fits perfectly!
