When it first come out I really liked it. At a local dealer they changed my fuel filter in my diesel, but didn't prime it sufficiently. Camping at 10k feet in Colorado my truck would not start in the morning. I hit on star and they had me pinpointed. They also put me in contact with the GM dealer in Durango. They sent a flatbed up, loaded my truck, and got me into Durango in time to get on the steam locomotive to Silverton. They picked us up on our return and my truck was ready.
Three years ago in Yosemite National Park I got shingles for the third time. I needed to get in touch with my doctor and have him send a prescription to the first town we would encounter outside of Kings Canyon where we were headed next. I was disappointed that I had Verison service before on star service. I found they had switched from satellite to cell towers. At least that's what a lady I contacted told me. So for me it's worthless. The three month free trial on our new Travers is up next week, but I cancelled three days ago before heading out for deer season.
