The ease of use, the flexibility in setting up multiple zones with different screens and content, the ability to add new screens at any time. I do not have anything negative to say about Truelink. It has been a very smooth experience from beginning to end. There are some minor glitches but they usually get fixed quickly. We have used this service for several years now and it has never really let us down. We have a pretty good idea of what we want when it comes to our media library. Being able to customize that with a variety of options is great!
