Easyrider, that thing looks like it would be wobbly if you had to tighten or loosen something that was tight.
I like wrenching on mine so I went with a Titan 1500Lb bike/ATV lift for stability. I'm real happy with it, but the one negative is it takes up a good bit of space. I chose this one because the platform raises to 45", which was about 8" higher than most I looked at.
I do like the Bestway inground lifts. I did consider one.
