I like that this program is easy enough for my husband who has been using it all his life, but advanced enough for me since he helps with computer issues sometimes! The fact that you can customize the programs so easily and have access from anywhere makes everything run smoothly without any glitches. Nothing yet other than making sure we are able to get updates if they come out in future versions of the software. Make certain your internet connection is fast/reliable (I use Verizon) because otherwise the site will be slow loading times; also make sure that updates are downloaded ASAP after purchase because there may be delays between when an update comes online and when it becomes available to download. Our previous version was not compatible at all with our current hardware and operating system which made working with the program very difficult. This new software solves those problems by allowing us to work more efficiently and effectively while still being able to keep up with daily tasks.
