I use the Torin stands. Left my car on a pair for a week at a time in front then rear. I think they are ANSI certified if that's of any significance. I like the base design which looks like it distributes the load over a flat base versus other stands that concentrate weight on 3 or 4 points. Potential danger is if the ground isn't hard enough the concentrated points may sink into the ground.
