I've got two HF aluminum floor jacks and they are not new. Newest one is 3 years old. One is standard pump, and one is the quick pump style. I've had no issues with either, and would buy another if I needed it.
HF gets a lot of bad press (deservedly on some items!) but the floor jacks sure have given me a lot of good service over the years I've had them. And I don't consider a floor jack a "critical" piece of equipment. I do consider jack stands critical! I'd never get under a car while on floor jacks, as I use them simply to lift, and then jack stands to hold the load.
