I've been using it for more than a year to study Hungarian, pretty regularly : 2 lessons a day, pretty much no streak break.

It's pretty good for the first steps, and to get some vocabulary. I can't follow a non-basic conversation, but I can pick up words from native speakers.

I'm now at the point where I should work on my own with more seriousness.

Overall, it's good to start learning a language, and to keep a regular practice, but it's not enough on its own to actually speak the language.
