"I really like EfficientPIM, I like being able to open a contact when I make a call and then recording the important points in the memo section, quickly add calendar events with the contact associated and set up tasks such as call back on a given date to confirm whatever we discussed doing. The inter-connectivity of contacts to events and tasks is critical for me. I compared nine PIM program before deciding on yours, most of them could not hold a candle to EfficientPIM. The only competitor you have as I see it is VueMinder which is in the same league as Efficient but the deciding factor between the two is EfficientPIM only crashed one time in ten days of testing and VueMinder crashed more often."

Overall, I am astonished by the number of features within this application and how intuitive the menu structure is. ..."
