I have two of those type of jacks in the garage, and they're okay for occasional use I suppose, but the rear castors will bend and twist about and the whole construction is less than I would prefer to have. Mine aren't the low profile jacks, but the construction is the same, and I paid about half of the cost of the linked one.
Costco do an excellent alloy low profile jack which (as soon as they put it back on special offer) I'm gonna have.
