I liked it for on-the-go studying. It is like having a pocket PDG study guide. (PDG Made Easy! App)

Your company is the reason I made SSgt, TSgt and MSgt first time! (PDG GOLD)

I just wanted to let you guys know that I won your product last year and finally made MSgt by 50 points! I beat my AFSC average by 14 points. Thanks McMillan!
