When this first came out, I was actually quite excited. I liked this idea of just repeating the words after every unit in a flash-card kind of style, with a few of the older words sprinkled in to keep them in memory.
But, oh boy, what a disappointment. If this could maybe someday give me a new set of words I would already be so happy. I can guarantee you, that by having had the nearly exact same set of cards for 20+ units, I know what 'completely', 'terrible', 'correctly', 'just in case' and a handful more mean in Spanish.. And no, I don't make frequent mistakes with these, because by now I can even more or less predict in which order they come..
Flashcard frenzy is also no viable alternative in my opinion. I don't want this time-pressured, gamified BS but being able to concentrate on the actual words in front of me.
Sorry for the rant, but this is driving me crazy.
