Be careful for refunds!!!
It is an excellent company to improve, especially pronunciation in any language. My 3 star rating is due to the lousy "refund" service. They renew your membership without notice, and when you claim a refund they tell you that you must read the almost hidden clauses of their contract. A dishonest and undesirable practice: therefore two stars for their service. For the rest, very efficient.
