I have a Garmin 1350 with lifetime maps and traffic. I have only taken one long trip with it, but it worked very well. Just make sure that you have the options set the way you want, especially regarding toll roads. I actually use it going back and forth to work. The traffic really does work. The first time it tried to redirect me, I did not really believe it, but it kept on trying to redirect me. I finally saw traffic in front of me coming to a complete stop and managed to get off the interstate, with some delay. After that I believe it.
