I've saved money and appreciate that there has been no downside to them. My wife, who mainly drives the car, has done several hundred miles on these tyres in all kinds of weather, and has noticed no change in performance, noise, or fuel economy with regard to the Continentals we had before. As for how long we expect them to last, it's a bit soon to tell, but I was also not too pleased with the lifespan of the original tyres.
