I like how easy it is set up once you have an account setup with them! They are very helpful when setting things out from scratch or making changes after they've been made by another party (like we did). It would be nice if there was more than one way that something could get transferred between accounts - maybe two different icons so users aren't confused about what each thing means? Otherwise as long as everything gets passed over correctly nothing major comes back at me unless someone's really trying hard :D.
