Lots of people die every year from vehicles falling off of jacks and crushing them. I nearly lost a foot 2 years ago from it. You NEVER get under a car that is only supported by a jack; that is almost the definition of Darwinism.

I was not even working under the car when it fell off the jack and pinched my foot. Another thing to remember:

The jack does not need to fail in order for the car to fall on you!

More likely the vehicle just slips off. Not the jack's fault. They're only designed for lifting and lowering. That's what happened to me.

Any floor jack w/ enough capacity is fine, since you are only using it to lift and lower the car. (Use jack stands). They sell Chinese floor jacks at every FLAPS and Sears, etc. Wayne sells good ones, but you get what you pay for and vice-versa.
