I have been very impressed with the service from Jepp. I get the botlang manual and the Jeppview electronic plate service and every 2 weeks the amendments turn up without a problem. I also use flight star which as a program I am very impressed with but it still has a few niggles that drive me nuts, like it not working with a Garmin GPS 196 and the eratic natire of the online database updates but otherwise Jepp provide a great service.
