Insync is a great place for IELTS preparation. I did my course via online mode. I never felt like missing the direct classes as the online classes were very interactive. Mr. Shane Jordan is an Amazing trainer. As a former IELTS examiner, he has great depth of knowledge about IELTS. His tricks and tips would definitely result in improvement. Moreover, he exposes us to the reality of the IELTS test, so even before taking the test, you can predict your performance. I would blindly vouch for Insync.
