The software is very easy to use, it has many features that are useful when managing our trips as well as having access from anywhere at any time with multiple devices! I do not have anything negative about this product so far but if there was something missing or improved i would like more options of customization such as being able to change colors etc.
There isn't much you can say bad about this program because everything works great. We used Pass agent desktop before we started using TripIt which helped us organize and schedule out trip details easily without needing two programs open at once.
