Anyone tested Dataguard Antikeylogger Ultimate?

Have anyone tried it? It has a lifetime licensing at $59 compared to spyshelter's $39 while having a 15 days fully featured trial. Top Ten Reviews placed it at #2 after Zemana although I have no faith on them. I personally tested it with Zemana test, which it is able to block totally while in Spyshelter test it blocks only the keylogging test. Actually in very near future I am going to write a review on it and run a week-long unlimited lifetime license giveaway of Dataguard Antikeylogger Ultimate. So, its very essential to me to know every detail of this. Can anyone spot any light on its effectiveness against real malwares? I am not familiar with keyloggers.
