Balance is a huge issue with the 2 post. You have to treat the lift like it actually is. It doesn't think. You do that. A car will fall off it, but it's not going to collapse within reason.
So just how big an issue.
Is it a matter of "Hey, you need to check every car every time and lift a little and see?
Or more like it is generally good, but if you have an odd vehicle like a pickup with most of the weight at one end, then watch out!
