I prefer a solar powered auto... they have some nice features for the
settings... response, shade and light time.. I have the Jackson
Hellraiser, and its a nice helmet.

Rich, now what if you forgot to push the button? My helmet won't
shut down for 15 minutes....and I've made it a habit to push the button
whenever I flip my helmet down.

I think its speedglas that has a chin activated shield...flex your jaw
and the face raises up...not sure
