@@kincaid549 If you over drive the ramps (go too far forward) the force applied on the end causes excessive stress on the middle of the ramp and they snap. Kind of like when you grap a twig at both ends and bend them until it snaps in the middle. Same concept.
A backup doesn’t hurt; you can always place a couple of jack stands under the vehicle as a second measure. For instance when I do brakes, I use jack stands along with a hydraulic jack and then I place the tires under the vehicle. So I have two backups.
If you want to lift the entire vehicle, then I would suggest jack stands or a quickjack - something of this nature that would get both the front and back off the ground.
No regrets at all. I use them on a regular basis and very happy with this purchase based on the vehicles I have. I use these ramps in many of my videos.
As long as the drain plug is the lowest point of the oil system, it will still drain fine. Therefore you can jack up only the front or use ramps and still have no issue changing the oil.
