I had it for years, and never used it...thought about canceling it, but finally used it this past Summer, and it saved my ass.
When I had an oil change and tire rotation, they didn't put one of the tires back on my truck correctly, and it fell of my truck while I was doing 75 on the highway. No joke. I felt this 'boom' and sparks starting shooting out of the back of my truck, and then I saw my left rear tire go rolling past me. It was surreal. It rolled down the highway, and then cut over to the other side, missing every damn car! The craziest thing is that this happened about 2 weeks after the tire rotation, and I drove about 500-600 miles in that time.....and of all the places for it to happen, it was almost directly across the highway from the place that did the rotation!! I can't make this sh*t up.
Anyways, triple-A was there immediately, and were very cool about it. Actually a cop stopped first, and he was like 'did your tire blow?' I said 'no, it's up there on the road somwhere.' He says 'Are you f'n sh*ting me?' and I just pointed at my missing tire. He went to look for the tire...and then he never came back. Awesome.
