Hi! How are you?
Talk specifically about italiki, can be hard learning other language if you don't look at for a good teacher. There are so much options to think about and you need to focus in your goals.
To me, until now, italiki works very well. I found some teachers that mach with my goals and now I'm testing what is the best method to me, who has better adherence to my learn skills.
I hope my answers can help you and be understanding too because I don't good enough in English yet. :)
