The fangs have saved me twice and once not. Both saves were going uphill onto a sidewalk with a wheelchair transition and the nose touched, fangs rolled and saved my ass. The "not" time the transition (a ditch in the pavement going up a steep hill) was too much for the fangs and I went down and rolled with the punch. Minimal damage to me or the board. I hit the back of my head hard enough to draw a little blood but don't feel any dumber than normal so am not going to buy a helmet quite yet. 500 + miles so far. BTW, I'm 74 and have taken (exactly) 4 falls (so far) LOL.
