I love how it is so user friendly! It's very organized for me as an admin person who has no idea what they are doing when comes time to send out emails or create reports etc.. The customer service that we get from their team members makes all worth while in my opinion!! Nothing at least not yet anyways but there was nothing i disliked about our experience using leadlite software either which made everything great. Just be sure your system can handle large amounts of data being uploaded/downloaded because once things start getting bigger than 100mb per file its going slow down like crazy. ! Be prepared if something goes wrong during transfer process (data loss) just contact support right away cause they will fix anything within minutes even after hours sometimes.
