Review for Shoei Transitions CWR-1 Photochromic Helmet Shield with Pinlock Pins

The shield works well. Darkens quickly in the sun and clears as light diminishes. My only concern is how gingerly I'm going to have to treat it when cleaning and how soon the photochemical properties will dissipate. I guess I wouldn't be concerned if I'd paid $50 for it. Good shield!
