I like that it's easy to use, has an intuitive interface with many features available at my fingertips! The program isn't perfect - sometimes when you're trying send something through there are some errors which can cause problems depending upon what item/package was sent or if its one of those where they have time outs waiting until someone responds (ie- tracking number doesn' work). It would be great however in order so we could see how long our packages were held by other companies as well!!
