I have a hein warner (not us company but us made) and I've used one of the HF aluminum jacks extensively. The HF aluminum jacks, especially the small 1.5 ton one, are compact, light, and very mobile. But all the non aluminum parts have had chrome peeling (always in a garage, never wet), and doing anything by axle vs by quarter causes a lot of flex that is uncomfortable and scary.
If you only need one, go with a real, steel, heavy one that weighs 100 lb. support your neighbor and their job instead of the Chinese, sink the money in an item that will pay for itself in no time, and get something from the first world.
