Have been on italki for two years. My teacher uses tprs and I’ve found it very valuable. It gives me a great opportunity to catch new things and explore nuances.
As an example, the other day we came across そっくり and used it as an opportunity to explore when to use that or -よう or -見たい.
Its also nice to be able to try out constgucts that seem correct from immersion, but end up sounding weird
