I like that it's very simple yet powerful tool which helps me manage my contacts quickly and easily without wasting time. It has all options required by any business owner who needs this software to organize his/her work effectively as well as saving resources of money. There are some minor bugs but they don't affect user experience negatively. The best feature about it - it's free! You can try out their demo version before making final decision whether or not you need such a complex program. If there was something more functional then maybe i would consider purchasing it from them instead of finding another one myself. Managing contact information within just few clicks makes life easier than ever.
