Used both PDG GOLD and PDG Advisor plus listened to the PDG audiobook for 6 months. I made SSgt my first time; 26 points above the cutoff!

I used PDG Advisor for the first time and it worked wonders. I made E-6 even with only a 15% promotion rate!!!

It will be an excellent tool for iPhone and iPad users. I love being able to test myself anywhere. (PDG Final Exams! App)
