It is a work horse ! Mine has had two full generations of hard constant use. I love it and would not give it up. Mine has the good old fashoned knee control , which I really love and wish new machines have one.
My sewing machine repair guy who "see's" my newer machine tells me ( about the old machine) just keep it oiled and clean it will run forever! If mine ever does finally wear out , I will be heartbroken and look to replace it with the same machine.
