A tad intimidated at first because the words and sentences are spoken at normal, native speeds. But I quickly fell in love with the content, usability, and integration of mobile / browser functionality... Well thought out layout and content; love that IKnow offers examples in both male and female voices. If youre willing to put the time and effort into IKnow, it absolutely works for learning vocabulary and sentence structure...worth the money for sure!
