Just stopping by to say this is a quality design jack pad. It survived accidental forgetfulness when I was rushing to go pick up my wife after swapping out all four wheels for the winter season (I was late picking up my wife BTW) about a week ago. I forgot one of the four jack pads under my Tesla Model 3, drove it for about 7 miles or so round trip and it survived not getting lost in the middle of the road somewhere. The magnet was strong enough to hold the jack pad onto the car for the entire short trip. I was expecting to lose the jack pad due to pot holes and irregular road pavements. Job well done on the design.
