I've had Rhino Ramps for 15 yrs and no issues- I use them on level concrete. You get the hang of launching a car up them after a few times: stab throttle, let off, brakes. I have two wood 2x12 sections I sit in front for low cars. Of course also have floor jacks and jack stands, but on my car I have to use ramps first, then jack and stands. I dont have a lift, the jack won't reach the front center jack point, and the jack goes where the jack stands go on the sides as I dont want to use the rocker pinch weld .
