Superb experience!
They offer free access to help build a solid foundation for learning Chinese, and the method they teach is highly effective. The only downside is that the free trial is so good, I’m seriously considering buying lifetime access, even though it’s a bit pricey by my standards. That said, you could argue that if it helps you become fluent in Mandarin Chinese, it’s definitely worth it. I strongly recommend this program to anyone learning Chinese.
