I like how easy it is for me as an individual user of this software product because everything can be done at my own pace! There are some features that would have been helpful if they were more customizable but other than those minor issues there really isn't anything else about PPI's service/product itself which needs improvement upon.
The best thing so far has definitely just being able use their services when ever needed due too them having such great customer support staff who always respond quickly whenever you need help via email etc..
