Jacks like that won't last long lifting 2 tons. Buy at least 2x the jack you expect to need, and it may last. So, don't lift more than 1000# with that one, and you'll be happier.
You ask if it's any good - that's a workable jack for an occasional weekend warrior, but if you're frequently fixing cars or trucks, it won't last and the short handle will get annoying.
