4 Pack Polyurethane Universal Medium Size Slotted Jack Pad Frame Rail Protector

Is this a good fit for Audi Q5?

Are these more durable than the black rubber ones sold by most other brands?

Is the slot the right depth for an 8th generation Honda Civic (2006 through 2011)?

The ad states "does not fit Trolley Jacks" but uses a photo of the device on a trolley jack. What prevents it?
