I like how easy it was to use, as well as all its features! It's very user friendly for new users but also has some advanced functionality if you know what buttons do exactly which can be confusing at first until your familiar with everything in this software package (which takes time). The best thing about using icompllii though are the reports we get back from our clients once they've gone through their training program - so much easier than having them send us emails or calls each month asking questions etc!!
