Sturdy, robust construction. Inspires confidence and extra safety with the pin it has (most similar ones do not have a pin)

good construction, sturdy tripods that make you feel safer than the others that fold. If you also take a rubber material and place it at the contact point with the chassis, then you have solved the problem of denting. On these, I lifted half the car in front, lowered the transmission, etc., since they can lift it to a sufficient height for you to comfortably get underneath and work, without your elbows hitting and being unable to turn... The pin they have for extra safety is also the reason I chose them, so pay attention to this very important detail before you settle on something.
