They are an Internet-based housing inspection platform, and their business feature is housing inspection. They must check their qualifications, business skills and familiarity with relevant national codes and standards for civil buildings, and they must take exams before they can take up their posts. Those with a favorable rating of less than 98% will be eliminated, just to recommend a truly professional and reliable housing inspector to the owners.
So, for your question, their service is great, and it is a new platform at present. For the sake of reputation, they should work harder to serve the owners.
