When using scissors jacks, I would recommend using two scissors jacks, like one on the front point and one at the rear point,It also takes seconds to destroy it. Today my jack has collapsed with car being raised...
to move up each jack point like one inch at the time, which help when turning the wrench, otherwise it might be too hard to do so.
Note: My floor jack has wheels, and I noticed that when using it, it rolls a little bit when lifting my car.
So regarding the @Mash scissor jack collapsing, I imagine that the scissor was a little bit bending when lifting the car.
Using two scissors could had prevented it by allowing to unscrew a little bit one of the scissor jacks,
while having the second scissor jack supporting the whole car for a moment,
to re-adjust the scissor jack position so it would not be bending anymore.
In my area, there have been several catalytic converters stolens during the night,
and recently one robber died after his scissor jack collapsed while he was under the car.
I would never crawl under my car with only a scissor jack supporting it, and would put first some stands to support the car weight.
