You can go to a retailer and demand a credit toward a new helmet. They have to honor it. Cascade and Warrior have both said as much.
Gee, you don't think I asked for that at LU ?!? No refunds, no vouchers and certainly no price other than what it costs to buy another helmet and more of the same...hold tight, this is a paperwork problem only, and any day now it will be resolved. Rinse and repeat. If Cascade were an automaker they'd be out of business.
