Are you using it to support the bike while you work on it?
If so HF, PepBoys, Walmart et al have hydraulic bike lifts which are far more stable and have about a 4" minimum height. Generally 50 bucks or so. Look like this, and you'll find it in several colors and marketed under different names and pricing, but they're all the same item.
I routinely lift 600-800 lb. bikes with one just like it. Just make sure you Loctite all the nuts and bolts when you assemble it. The handle comes off and it's pretty compact whe not in use.
The race stands are pretty useless for doing repairs, IMO.
