Has anyone tried these?

I have 4 6 ton jackstands. Use them when necessary. I do have a hoist and various other stands.
I have two of them, use them on front, work great. Cradles the tires so won't roll out. I use two hand-made wooden stands for the rear. However, I am not comfortable using them on the HD2500, whereas the wooden stands are rock solid. A ton of floor clearance.
