Two weeks ago, my year-old C3s sun visor jammed in the up position. I emailed Schuberth USA, and they sent a prepaid UPS shipping label so I could return it for service. Turnaround was only 4 days, and they repaired the sun visor and replaced the shield and Pinlock because of problems with it also. No charge.
Just thought I'd pass this on to say that Schuberth stands behind their products.
