I don't practice llanteria
Funny, I grew up with the widow maker. It was, literally, the only jack I knew for nearly my first full decade of driving...never had a problem with it. Hell, I've even used it for jacking up a boat trailer, never had an issue. Do they physically fail, or cars just fall off? If they just fall off, it's user error.
But they do require due diligence to make sure you're on flat, solid ground, the positioning on the pinch weld is correct, and that the car is chok'd to make sure it doesn't move, *at all*.
Tried to get it off while on the widowmaker?
Not to mention, how many roadside shoulders are level enough to use the widowmaker?
Ya good luck.
Agreed, the design is pretty elegant, but it's use is limited and doesn't factor real world scenarios.
Shoulders? That's why the car rolled on me. Long downhill in WV, the flattest place I could stop still had a decent grade on it. Just took a little inventiveness for wheel chocks and all was good.
Real-world? My space saver jacks have had some MILES on them, if you can call it that. I don't think you understand my bad luck with tires!
