We popped in some batteries to check it out and everything works on it. Ken even used the seat belt cutter to cut some old fabric in half to see how sharp it was and it's pretty darn sharp. This is a great product to keep in an emergency kit or your car.
If you'd like to order one of these Auto Glass Breaker's, you can do so here.
I give this product 5 out of 5 stars
