It has been very easy for me to use this software because it's so user friendly! I love all of the features that are available in this program. The best feature about this product is how many conversion options there are! I am able to easily do multiple conversions at one time with this fantastic piece of software. What would be even better if you could upload your own images into the converter as well as being able to edit them before they're uploaded. Great product! There was nothing bad or negative at all. A great way to save myself tons of work time by converting my email contacts from different formats like.csv files etc.
