Best Chinese 1o1 online classes

Having stayed in China for already a few years, I have never really gotten into learning Chinese seriously. I took a few trial classes from other schools before, but never really went too far. Finally, for my new job I had to improve my skills, so I tried Silks 1o1 classes and never looked back. They are well structure, highly flexible and the teacher is beyond patient. The platform they are using is very easy to use, with apps for Win and Android., support is great, so far, no complaints. Highly recommended!
