I am an intermediate French student, but I am starting with the beginner lessons as review because I rarely have an opportunity to listen to native French speakers or to practice speaking. I am finding the lessons very helpful to develop my "ear" and my accent. The explanations of the grammar points within the dialogues are very clear and the opportunities to practice speaking are great.
I have used several online French courses and this is by far the best, though Babbel is quite also.
