I have the same jack From California Car Cover, on my car I had to add a 1"X4" block of wood under it to actually lift a rear wheel off the ground. But it does the job.
I like it as we usually take our car on at least 1 5-7 day trip and I wanted to have a way to remove a tire for inspection/plugging if needed.
