feedback and thoughts regarding “Japanese mastery Method” course

I’d like to know your feedback and thoughts regarding “Japanese mastery Method” course
I’d be very very thankful if someone could put some time and write a detailed a review about the course and their experience (how is the course structure , how much does it cover from N5 to N1, how much time needed to complete the course , your opinion about the methodology used to deliver the course and how much did you get out of the course)

It’s from the same guy who made “Japanese made easy” podcast

It’s from the same company who made the russian made easy and russian accelerator so the course so it uses the same techniques used in RA such as contextual learning, super literal translation and pattern recognition

Note: I’ve contacted the teacher and said it covers till N3 in terms of listening and vocabulary and he will be adding a course dedicated to the particles in the near future and he also said the course main goal is the speaking and the conversation skills so there’s no focus on kanji or or writing or reading
