The best part is it's accuracy rate which I have seen as 99%+ for all its features (KYC/AML) so far! It sometimes takes time before it starts working but once you get used to it this doesn't really matter much anymore since we are using trustchecker frequently now.
We use their KYC tool only when our team members go outside India or want verification of documents from other countries where they work at times like those mentioned above - otherwise everything else can be done within Indian borders without any issues.
