RocwooD 3 Ton Axle Stands

I found these axle stands difficult to set up under the car. I wish I’d purchased axle stands with a simple hole and dowel pin on the shaft. I understand the principle of the ratchet and triangular peg on these axle stands but the safety peg easily gets disconnected at the slightest touch. I for one won’t use them again they’re too awkward.
