Testimonials & Reviews

"I use your program, EfficientPIM since january. It's absolutely great, but I have a little problem with it. Usually I use 2 computers without any connection between each other. I want to use EfficientPIM on both computers, with the same database. Now I do this with a flash drive."

- Tamas Vereb, March 2012

"What was the biggest influence on your decision to purchase EfficientPIM? My answer: I find it covers my PIM needs in one package and has proved reliable."

- Thomas Tuddenham, April 2012

"I've been setting up the diary today & I am just as pleased with this version as I am with the Efficient PIM. There are a few variations which I think are beneficial to the whole package.I look forward to many months, or maybe years, of using this organizer. Well Done!"
