The best thing about this product is that it easily integrates with other software packages such as Excel so you can have your data in one place for easy access. It's also very customizable which allows me great flexibility when creating my plans. I like how quickly the program loads once installed but sometimes it takes awhile before some features are accessible if they haven't loaded yet. This isn't really an issue though since everything works well together seamlessly. We use raincad mainly because we need our water plan updated regularly throughout the year due to changes from city ordinances or new developments nearby.
