Justin Case Ground Triangle

I bought this to store in my trunk in case my car breaks down one day. I've had a belt snap on a busy highway before. Any state trooper will tell you that any sign that gives passing motorist a heads-up to be careful as they're passing your car could make a big difference. Anyway, the black base is heavy, not super-heavy (if it's really windy, you might need to put something heavier on it). The triangle is bright and large. HIGHLY REFLECTIVE. For $6, I haven't seen a better price. These things go for twice as much on amazon. Thanks Walmart!
